Question

two objects that are the same shape but not the same size are _______. congruent complementary similar vertical

Explanation:

• "Congruent" means objects are the same shape and size, so this is incorrect.
• "Complementary" relates to angles adding up to 90 degrees, not shape/size, so incorrect.
• "Similar" in geometry means figures have the same shape (corresponding angles equal, corresponding sides in proportion) but not necessarily the same size, which matches the description.
• "Vertical" refers to angles opposite each other when two lines intersect, not shape/size, so incorrect.

Answer:

C. Similar
