# AASTriangle

AASTriangle[α,β,a]
returns a filled triangle with angles α and β and side length a, where a is adjacent to one angle only.

## DetailsDetails

• AASTriangle is also known as angle-angle-side triangle.
• AASTriangle can be used as a primitive in 2D graphics and as a geometric region in 2D.
• The given (blue) and computed (red) parameters for an AASTriangle:
• AASTriangle returns a Triangle with at the origin, on the positive axis, and in the half-plane .
• AASTriangle allows the length a to be any positive number and the angles α and β to be positive such that α+β<π.
