Question

identifying congruent shapes on a grid

Explanation:

Step1: Check the first pair of triangles

Congruent shapes have the same size and shape. The first pair of triangles have different sizes (one is larger than the other), so they are not congruent.

Step2: Check the first pair of circles

The first pair of circles have different sizes (one is larger than the other), so they are not congruent.

Step3: Check the second pair of L - shaped figures

The second pair of L - shaped figures have the same size and shape. If we rotate or translate one of them, it can overlap the other exactly. So they are congruent.

Step4: Check the second pair of rectangles

The second pair of rectangles have different sizes (one is larger than the other), so they are not congruent.

Answer:

First pair (triangles): No, First pair (circles): No, Second pair (L - shaped): Yes, Second pair (rectangles): No
