Question

answer attempt 1 out of 2
the two triangles are related by
, so the triangles

Explanation:

Step1: Identify Triangle Relations

Check the triangles: one has a marked side and angle, the other too. A common relation for triangles with a pair of equal angles and a pair of equal sides (or via transformation) is reflection (a type of congruence transformation). Congruent triangles have equal sides/angles, so if related by reflection, they are congruent.

Step2: Confirm Congruence

Reflection is a rigid transformation (preserves size/shape), so triangles related by reflection are congruent ($\cong$).

Answer:

The two triangles are related by \(\boldsymbol{\text{reflection}}\), so the triangles \(\boldsymbol{\cong}\) (are congruent).
