Demonstration of the AA Similarity Postulate
The two triangles are built based upon the two angles given by sliders and the position of the two bottom points of the triangle. Click the checkbox to see if that is enough information to have two similar triangles. The two given angles may be changed with the sliders and the positions of points A, B, C, and D may also be changed by dragging them.
