Do you know how to prove two triangles similar?

anonymous · Answer

Yes.

anonymous · Answer

They have to have equal angles and corresponding sides

mathstudent55 · Answer

One way is by showing two angles of one triangle are congruent to two angles of the other triangle. That is AA.

mertsj · Answer

Equal angles is enough to prove them similar.  Do those two triangles have equal angles?

mathstudent55 · Answer

For AA all you need is two angles of one triangle and two angles of the other triangle.

mathstudent55 · Answer

Look at triangle CAT. Can you figure out the measure of angle A?

anonymous · Answer

so there is not enough information.

mathstudent55 · Answer

Not so fast.

anonymous · Answer

yes. 106 is the other measure.

anonymous · Answer

Anlge A is $$180-(87+13)=80 {}^{\circ} $$

Look at triangle CAT. Can you figure out the measure of angle A?

mertsj · Answer

ISABELL!!!  We just discussed this.  Find all the angles of both triangles.  Are they the same?
