WebAug 29, 2024 · If we know that the length of the base of triangle $\Delta$ ABC is 42, we can use this to find the length of the base of the other similar triangle. First, as with working … WebExample: 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).
