Are the two triangles below similar?

Yes, the two similar triangles because there are two pairs of congruent corresponding angles

Step-by-step explanation:

from the give figure:

In ΔUTV

By angle sum  property of triangle;

Substitute the given values;

⇒

Now, In ΔUTV and ΔYXW

AA similarity postulate states that the two triangles are similar if they have two corresponding angles that are congruent or equal in measure.

so, by AA similarity;
