(AA) Angle – Angle – Similarity – Theorem
Angle – Angle – Similarity If two angles of a triangle are respectively equal to two angles of another triangle, then the two triangles are similar. Given: Two △ABC and △PQR such that ∠B = ∠Q, and ∠C = ∠R To prove: △ABC ~ △PQR Proof: In △ABC, ∠A + ∠B +∠C = 1800….(1) by angle sum property In △PQR∠P + […]
