How do you tell if two triangles are similar? I know that the angles must be congruent, and the sides must be proportional. How do you determine if the sides are proportional?
Here is the problem:
Are any of the three triangles similar? If so, write the appropriate similarity statement.
1st triangle: CAB; CA=4; CB=4; AB=5; Angles A and B are congruent.
2nd triangle: PRQ; PR=8; PQ=10; RQ not listed
3rd triangle: XYZ; XZ=8; ZY=8; XY not listed
*On triangles PRQ and XYZ, angles P and Z are congruent.
