Question

what mathematical relationship describes the sides of similar figures? \
\bigcirc parallel \
\bigcirc perpendicular \
\bigcirc equal \
\bigcirc proportional

Explanation:

To determine the mathematical relationship of sides in similar figures, we analyze each option:

• "Parallel" describes the orientation of lines, not side relationships in similar figures.
• "Perpendicular" also describes line orientation, not side relationships.
• "Equal" would apply to congruent figures, not similar figures (similar figures have sides that are proportional, not necessarily equal).
• "Proportional" means the ratios of corresponding sides of similar figures are equal, which is the definition of similar figures.

Answer:

D. Proportional
