How many angles need to be the same in a triangle that is similar to another?(1 point)

Answer 1

For two triangles to be similar, it is sufficient for just one pair of corresponding angles to be equal. However, generally, in practice, we often check that all three corresponding angles are equal, since if two angles in one triangle are equal to two angles in another triangle, then the third angles must also be equal (by the triangle sum property). Thus, while one angle is enough to establish similarity, typically at least two angles are compared.
