Having the same size and shape.

Having the same size and shape.

• A. Similar
• B. Equal
• C. Congruent
• D. Identical

Answer: (C)

Congruence is about having the same size and shape. Two figures are congruent if you can move one with rigid motions—such as sliding, turning, or flipping—it so that it lies exactly on top of the other without changing its size or shape. That’s why having the same size and shape is described by the term congruent. This is different from similar, which means the figures have the same shape but can differ in size (there may be a scale factor). It’s not described as equal for whole figures—equal is typically used for lengths or measurements, not the figures themselves. And identical would imply they are the exact same object in the same position, whereas congruent figures can be in different locations or orientations but still match perfectly when overlaid.
