WebAA (or AAA) or Angle-Angle Similarity. If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other. From the figure given above, if ∠ A = ∠X and ∠ C = ∠Z then ΔABC ~ΔXYZ. From the result obtained, we can easily say that, AB/XY = BC/YZ = AC/XZ. WebProof of Angle bisector theorem. We can easily prove the angle bisector theorem, by using trigonometry here. In triangles ABD and ACD (in the above figure) using the law of sines, we can write; A B B D = s i n ∠ B D A s i n ∠ B A D …. ( 1) A C D C = s i …
