1. The triangles are not similar
2. The triangles are similar by AA postulate
Triangle STU is similar to triangle WVU
Similar triangles are triangles are triangles with equal corresponding angles and equal side ratio.
1. Since the ratio of the corresponding sides are equal, then we can check if the triangles are similar.
21/27 is not equal to 10/14
therefore, the triangles are not similar.
2. angle SUT is congruent to angle WUV
angle T = angle V
therefore, triangle STU is similar to triangle WVU by AA postulate of similarity.
