Question

congruent? yes no similar? yes no
congruent? yes no similar? yes no
congruent? yes no similar? yes no
congruent? yes no similar? yes no

Explanation:

Step1: Recall congruent and similar definitions

Congruent figures have same shape and size. Similar figures have same shape but not necessarily same size.

Step2: Analyze first - pair (rectangles)

The two rectangles have different side - length ratios. So they are neither congruent nor similar.
Congruent? No; Similar? No

Step3: Analyze second - pair (L - shaped figures)

The two L - shaped figures have different orientations and sizes, and the ratios of their corresponding sides are not equal. So they are neither congruent nor similar.
Congruent? No; Similar? No

Step4: Analyze third - pair (triangles)

The two triangles have the same shape (right - angled triangles) but different sizes. They are similar (by AA similarity as the angles are equal) but not congruent.
Congruent? No; Similar? Yes

Step5: Analyze fourth - pair (circle and ellipse)

A circle and an ellipse have different shapes. So they are neither congruent nor similar.
Congruent? No; Similar? No

Answer:

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