Question

PLEASE RESPOND ASAP!!!! Four tangents are drawn from E to two concentric circles. A, B, C, and D are the points of tangency. Can you name as many pairs of congruent triangles as possible and tell how you can show each pair is congruent?

Answer 1

There are 2 pairs of congruent angles (equal)

Triangles that have their sides inside the same circle are congruent triangles:

The ones with sides CD and AB (outside ones, inside the big circle)

And the ones with sides BO and OC (interior ones, inside the small circle)
