Question

congruent? yes no similar? yes no (repeated for four sets of shapes)

Explanation:

Step1: Recall congruence and similarity definitions

Congruent figures have same shape and size. Similar figures have same shape.

Step2: Analyze first - pair (L - shaped figures)

The two L - shaped figures are of different sizes, so they are not congruent. But they have the same shape, so they are similar.

Step3: Analyze second - pair (circles)

The two circles have the same size and shape, so they are congruent. Since congruent figures are also similar, they are similar.

Step4: Analyze third - pair (triangles)

The two triangles have different side - lengths, so they are not congruent. But they have the same angle measures (assuming they are right - angled triangles with the same angle ratios), so they are similar.

Step5: Analyze fourth - pair (rectangles)

The two rectangles have different side - length ratios, so they are not similar. Also, they are not of the same size, so they are not congruent.

Answer:

First pair: Congruent? No, Similar? Yes
Second pair: Congruent? Yes, Similar? Yes
Third pair: Congruent? No, Similar? Yes
Fourth pair: Congruent? No, Similar? No
