Question

which pairs of figures below are congruent?

Explanation:

Step1: Analyze first pair

The first figure is an oval - shaped figure, the second is a circle. Their shapes are different, so they are not congruent.

Step2: Analyze second pair

The two triangles have different sizes (the second triangle is larger than the first), so they are not congruent.

Step3: Analyze third pair

The two L - like figures have the same shape and size (one can be transformed to match the other through rotation or reflection), so they are congruent.

Step4: Analyze fourth pair

One figure is a rectangle (length and width different), the other is a square (length and width equal). Their shapes (and side - length ratios) are different, so they are not congruent.

Answer:

1. First pair (oval and circle): No
2. Second pair (two triangles): No
3. Third pair (two L - like figures): Yes
4. Fourth pair (two rectangles): No
