State if the triangles in each pair are similar. If so, state how you know they are similar.
Zarrin [17]

Answer:

<em>A) similar; SAS similarity.</em>

Step-by-step explanation:

<u>SAS Triangle Similarity</u>

The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar.

We are given two triangles BCD and JKL. Sides DB and JL have a ratio of 90/20 = 4.5

Sides JK and BC have a ratio of 81/18 = 4.5

Since both sides are proportional and their included angle of 43° are congruent, then both triangles are similar, SAS similarity.

A) similar; SAS similarity.
