If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. Answer and Explanation: (A) We use three similar triangles to prove the Pythagorean theorem. Let quadrilateral {eq}ABCD {/...
Hence, △ABC and △DEF are not similar.(6)In △DEF, by sum of angles of triangles, we know that,∠D+ ∠E+∠F = 180°⇒70° +80° +∠F = 180°⇒∠F = 180°- 70°-80°⇒∠F =30°Similarly, In △PQR,∠P+ ∠Q+ ∠R = 180 (Sum of angles of △)⇒∠P+80°+...
