Question 8

Consider the triangles.

Which statement is true?

Accepted Answer

The triangles are similar because of angle-angle

criterion.

Answer

The triangles are congruent because of angle-angle

criterion.

Answer

The triangles are neither similar nor congruent

because angle-angle criterion has not been met.

Answer

There is not enough information to determine

similarity or congruence.

Accepted Answer

The triangles are similar because of angle-angle

criterion.

Answer

The triangles are congruent because of angle-angle

criterion.

Answer

The triangles are neither similar nor congruent

because angle-angle criterion has not been met.

Answer

There is not enough information to determine

similarity or congruence.
