Question

which pairs of figures below are congruent?

Explanation:

Step1: Understand congruent figures

Congruent figures have the same shape and size.

Step2: Analyze the first pair

The two L - shaped figures have the same shape and size when we consider their side lengths (by counting the grid units).

Step3: Analyze the second pair

The top rectangle has different side lengths (counting grid units) compared to the bottom rectangle.

Step4: Analyze the third pair

The two circles have the same radius (counting grid units for diameter), so same size and shape.

Step5: Analyze the fourth pair

The two triangles have different side lengths (counting grid units).

Answer:

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