The figure shows triangle PQR and line segment AB, which is parallel to QR: Is triangle PQR similar to triangle PAB? Explain using what you know about triangle similarity. (5 points)

Yes, they are. Both triangles are right.

Step-by-step explanation:

Look at the shape of both of the triangles (marked by the lines of the arrows.) If you know your types of triangles, you can see that both of them are right.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

where are the choices?
