Proving that two triangles are congruent by AAS can be verified when two angles and a non-included side in the first triangle are equal to their corresponding two angles and non-included side in the second triangle.
For the given parallelogram (check attachment): angle AXB = angle CXD (opposite angle) angle ABX = angle CDX (alternate angles) AB = CD (opposite sides in parallelogram are equal) Therefore, <span>Triangle AXB is congruent to triangle CXD.</span>
Step-by-step explanation: How I got this answer is that 4/5 of George's collection are flags right? So I divided 4/5 by 2 to get 0.4 or 2/5. Hope this helps!!
