Question

ratios, proportions, and measurement identifying congruent shapes on a grid congruent? yes no yes no congruent? yes no yes no

Explanation:

Step1: Check congruence for first pair (rectangles)

Congruent shapes have same size and shape. First pair of rectangles have different side - length ratios (one is more'square' and the other is more'rectangular').

Step2: Check congruence for second pair (pentagon and trapezoid)

Pentagon has 5 sides, trapezoid has 4 sides. Different number of sides means different shape.

Step3: Check congruence for third pair (circles)

Circles have same shape (all circles are similar in shape) and same size (same radius as they look identical in the grid).

Step4: Check congruence for fourth pair (triangles)

Triangles have different side - lengths (one is smaller than the other).

Answer:

First pair: No, Second pair: No, Third pair: Yes, Fourth pair: No
