Angles

By: Tim Lehman

Given:

Construction:

By using the two angles given, we can create a triangle similar to the triangle we desire. We then can find the perimeter of this triangle and use it to find the proper ratio to cut the given perimeter and find the length of each side.

Above, the triangle **AXY** is constructed
such that angle **A** equals the given angle **A**, angle
**X** equals the given angle **B**, and **AX** is equal
to the given perimeter.

Now, all that remains is to construct a triangle
similar to **AXY** with side lengths as above.
