In RST,RS=10,RT=15, and m∠R=32. In …Example: these two triangles are similar: If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°. In this case the missing angle is 180° − (72° + 35°) = 73°. So AA could also be called AAA (because when two angles are equal, all three angles must be equal).Dec 15, 2022 · Example 20: Prove that the line segments joining the mid points of the sides of a triangle form four triangles, each of which is similar to the original triangle.
