Question

which set has four congruent shapes?

Explanation:

Define congruence

Congruent shapes have the exact same size and shape, though they may be rotated, reflected, or translated.

Analyze each option

• Option 1: Four right triangles of different sizes and proportions (similar or different, but not congruent).
• Option 2: Four pentagons of different sizes and orientations (not congruent).
• Option 3: Four triangles with different side lengths and angles (not congruent).
• Option 4: Four trapezoids of the exact same size and shape, shown in different orientations (congruent).

Answer:

• (A) Four right triangles of different sizes
• (B) Four pentagons of different sizes
• (C) Four triangles of different shapes
• (D) Four trapezoids of the same size in different orientations (Correct answer)
