I need to draw a trapezoid and would like to constrain the angles to be equal. This way, I can change the length of the top or bottom, and the angles will be correct.

Is there any way to constrain two angles in a sketch to be equal?

Link values or Global Variables can do this. Take a look a the following link from the 2014 online help, it will walk you though the process.

Here is the alternative method using Global Variables.

use symmetry
