Math Problem Statement

Based on the triangles shown, which similarity statement about the fourth pair of triangles is true and can be used to complete the table?

Solution

In the image, four pairs of similar triangles are shown. To determine the correct similarity statement for the fourth pair of triangles (Triangle TUVTUV and Triangle PQRPQR):

Step-by-Step Analysis:

  1. Angle Matching:

    • For triangle TUVTUV:

      • T=85\angle T = 85^\circ
      • V=66\angle V = 66^\circ
      • U=29\angle U = 29^\circ (because the sum of angles in a triangle is 180180^\circ)
    • For triangle PQRPQR:

      • P=85\angle P = 85^\circ
      • R=66\angle R = 66^\circ
      • Q=29\angle Q = 29^\circ (similarly from triangle angle sum property)
  2. Corresponding Angles: Since the angles are the same, the triangles are similar by the AA (Angle-Angle) Similarity criterion. Now, we need to match the corresponding vertices:

    • T\angle T corresponds to P\angle P (both are 8585^\circ),
    • U\angle U corresponds to Q\angle Q (both are 2929^\circ),
    • V\angle V corresponds to R\angle R (both are 6666^\circ).

Conclusion:

The correct similarity statement is Triangle TUVTrianglePQRTUV \sim Triangle PQR, since the vertices match based on corresponding angles.

Tip: Remember that corresponding angles in similar triangles always match, and their sides are proportional.
