If rectangle A is congruent to rectangle B, the perimeter of both rectangles must be...?
By definition congruent rectangles are rectangles that have the same area and the same perimeter.
The same.
Are the rectangles congruent?
Congruent rectangles are identical in every way - they have the exact same length, width, area, and perimeter. You could place one on top of the other and they would match perfectly!
Similar rectangles have the same shape but different sizes. Their sides are proportional but not equal. Only congruent rectangles have identical perimeters.
Not necessarily! If you know the rectangles are congruent, their perimeters must be equal by definition. The congruence tells you everything about their measurements.
Yes! For example, a 3×5 rectangle and a 2×6 rectangle both have perimeter 16, but they're not congruent because their dimensions are different.
