# Vector triangles

Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016

1. So I've got these forces acting on an object and it wants me to create a vector triangle (it's in equilibrium).
How do you work out the angles in the triangle when you are just given the angles to the horizontal? I worked it out by making a right angled triangle for T1 and T2 (bit hard to explain) but was wondering what the best way to do it is because in textbooks they don't tell you how you find the angles. Rough sketch of what the triangle would look like below:

2. you work ou the angle to the vertical force by minusing 90 and the horizontal angles. To get to the vertical which is the weight in this case.

So you do -90 - horizontal angle? Or am I getting the wrong idea?
4. 90-horizontal angle=Angle to the vertical

90-horizontal angle=Angle to the vertical
Thanks, makes a lot more sense now, only problem is with vector T2 because it goes in the opposite direction... The rule still works but I was kinda struggling to visualize it, am I getting the right idea here?

6. here is my an image if this helps.

7. Yeah that helps a lot, thanks
