Question

which pairs of figures below are congruent?
(the chart part is omitted as per requirements, only the text part is retained: which pairs of figures below are congruent?)

Explanation:

Step1: Check first pair (circles)

Congruent figures have equal size/shape. The two circles have different radii, so they are not congruent.

Step2: Check second pair (irregular shapes)

The two shapes have identical size and shape (one is a reflection of the other, which preserves congruence), so they are congruent.

Step3: Check third pair (triangles)

The triangles have different side lengths/sizes, so they are not congruent.

Step4: Check fourth pair (rectangles)

The rectangles have identical side lengths (same width and height on the grid), so they are congruent.

Answer:

1. First pair: No
2. Second pair: Yes
3. Third pair: No
4. Fourth pair: Yes
