How to figure out the triangle

Show Transcript

okay so this is a video in regards to the third triangle that you're asked to draw and some trouble and that because of the math is involved in trying to figure out the triangle so what am I do is go ahead and for all the triangle here so I can figure out where things are things I know I know this is going to be 90° I know this the a-side I know that this is going to be the B-side and this is the seaside so this is the standard Pythagorean theorem that you know I'm hopefully from your geometry class with a squared plus b squared equals c squared 60 degrees okay and we know that the degrees in the Triangle are going to add up to 180 so we know that's 90 + 60 plus tax is going to equal 180 so we know then that this axe is going to equal 30 degrees so we know a lot already about the triangle now there's no information about the triangle in terms of sizing you get to decide how big the triangles going to be so I'm just going to start by saying that a is going to be 500 millimeters long okay once I know I have one side of a triangle like this that is a 90 degree triangle with a 60 degree angle in it these are special triangles that will allow us to figure out the flow meter so just as I can do a screen for B squared equals c squared to get the length of a c i could also I also know that in this type of triangle has a ratio of one that equals are trying here so is the first length B is the second life in C is the third length is a 2 to 1 ratio here are one and two so actually even know that this city is going to be 1000 so I already know that piece of information also do that right you know Ace word which would be 500 squared plus b squared equals 1000 squared and then I can go ahead and do the math to figure out what what be is going to be but there's also of course the other solutions for thanks I'm so I can give you additional help by telling you that if you go to the you right triangle calculator you can go ahead and figure this out yourself cuz you can I've already done this have put this in so this one is going to be 60 right and then this one I'm going to make 500 so now I've got busy here and if I say calculate that actually calculus everything for so you'll see hear that and it does tell me that a is 500 and B is going to be 866 I'm and then see is thousand just like mint okay so now we have all of our measurements on the triangle we can go back to thinking about how's it going to happen for the robot is going to be 500 mm now it's best if we do this with the heading so we know that 0 having if we go straight forward and it's a 90 degree heading and a 180 and 270 okay so that's how we're going to use the heading command and we're going to drive up our 500 and stuff so what we need to do is turn to create the triangle answer if I'm the triangle say it's not a very good I need to know the angle from 0 right here the rotation to hear about Sabaton teaching is the one that I'm interested in so how would I create a 60 degree angle in here well if I know this is 0 and I know this is 180 and I 60 away from that and I know this angle right here is going to be a hundred and twenty so at this point I'm going to 120 and I'm heading off at 1:20 now obviously it will be exactly 120 can you take us on 120 and we're going to travel for 1000 mm based on this but you already figured out once we get to this location again we have this Arlo current location which is running at 120 and we're going to need to get all the way to 270 because we want to head straight back across the peace we're heading is going to be 270 so from zero all the way around that's going to be 270 so I'm running a 270 right here okay so are my position for all the pieces I have to do that's true Cody in General Tso now I'm going to go to my XBR and I'm going to figure out what I want to do so first thing I'm looking to do is go to my I want to go ahead and put the pen down cuz I'm going to draw and select my color and you go with and now I have my pen in position so the first thing I knew is that at zero she's right here I need to drive forward and I'm just going to drive forward the distance that I told it to draw which was 500 okay so there we go driving forward 500 so once I get to that drive forward 100 then I'm going to go ahead and make the right turn cuz that's now at the top of the triangle that's and I'm going to have to make my hundred and twenty degrees turn so now I'm turning right and I'm going to rotate but I have to rotate until I get to The Heading so this is where we are run the wait until statements so I'm going to go ahead and say wait until and then we go to our sensing and we do you drive heading simple. I am not going to do my equals to first so I'm going to drop my equals to in here and then I'm going to select my drive had all my drive heading to be in degrees and then I need to go ahead and tell it the number of degrees now we know that 120 you probably will carry too much momentum so we're going to go ahead and put a little bit lesson okay sooner we know what's going to drive at 19016 return to that point at 1:19 we're going to have it go ahead and drive forward again and in this case we're looking at next portion of the triangle which is the fouls and right here so I'm going to go ahead and have a drive for word thousand and then I mean how to turn right again and now I need to have a drive forward I reach this point right here I need to complete this 270 degree he hadn't so right now I'm running out of 120 heading and now I'm going to go back and do the same thing I just did witches go to wait until and I'm going to go ahead and select mind equals 2 and then my dried wedding this time I'm I'm going to get to 270 so again to 68 on my turns elementum pieces are two terms in there one greet each one and then I'm going to drive forward now I'm just going to drive forward for the distance that we figured which was going to be 866 million and then I would say okay so that's what happened I want to test it out and see how it goes to see where I ended up on you so there's my first forward and I'm turning on to The Heading Springsteen's band so I'm just rotating there and that's a problem swimming where we went words wrong here or we sent to use I'm a fan of the Eagles I'm going to go ahead and say as long as it is less than see if this works better are we going I'm getting my trial going correctly going to spin again cuz he's not going to like to eat not sure why I can't get that equals to work correctly but I dropped that I'm going to go ahead and stop and reset and I'm going to switch that weight on steroids. 68 I know where she gets it wrong you yesterday the distance is 500 there's my rotation rotating back down rotating again I'm coming back finish my triangle area so it looks like it was still about 122 on the turn their so I think I want to go ahead and the crease this and take it down to 118 set alarm for 11 a.m. for closer 121 on the rotation and that was much better now so am I heading up to 70 was good I could try 117 here I didn't get any beholders shorts or where I wanted to be and I locations about the same heading to 12160 it's pretty close and there is there's my triangle okay so if that helps you out again nothing here is is right here it's on the mass so as Mister I'd mr. Chrome like to say math is quite useful and this case is very helpful in getting your robot to complete a right angle triangle with a 60 degree and again that is the special relationship here so you can figure that out but again calculator.net will help you figure that also okay thank you
