# In Exercises 5 to 8, name the method ( A A , S S S ~ ,   o r   S A S ~ ) that is used to show that the triangles are similar. ∠ T ≅ ∠ W and ∠ R ≅ ∠ U To determine

To name:

The method that is used to show that the triangles are similar.

Explanation

Given:

The triangles,

TW and RU

Approach:

Two polygons are similar if and only if two conditions are satisfied.

1. All pairs of corresponding angles are congruent.

2. All pairs of corresponding sides are proportional.

Definitions:

AA:

If the two angles of one triangle are congruent to the two angles of another triangle, then the triangles are similar.

SAS:

If an angle of one triangle is congruent to an angle of a second triangle and the pairs of sides including the angles are proportional (in length), then the triangles are similar
