Answer:
Not similar
Explanation:
Similar triangles have
- corresponding angles are congruent
- corresponding sides are in proportion
From the diagram you can see that these two triangles have one pair of congruent right angles (with the measure of 90°), but the rest angles are not congruent (one triangle has angles with the measures 60° and 30° while the other triangle has angles with the measures 45° and 45°).
So, these triangles are not similar.
