Question

matching sides are called; congruent sides; the same; corresponding sides; corresponding angles

Explanation:

In geometry, when dealing with similar or congruent figures, the matching (or corresponding) sides between the figures are specifically referred to as "corresponding sides". "Congruent sides" emphasizes sides being equal in length (a property), "The Same" is too vague, and "Corresponding Angles" refers to angles, not sides. So the correct term for matching sides is "Corresponding Sides".

Answer:

C. Corresponding Sides
