Question

which pairs of figures below are congruent?

Explanation:

Step1: Check congruence for first pair (circles)

Congruent figures have same shape and size. The two circles have different sizes (radii), so they are not congruent.

Step2: Check congruence for second pair (shapes like “Π” and “Γ”)

The two shapes have different structures (one has two vertical segments on left, the other on right in a different configuration), so they are not congruent.

Step3: Check congruence for third pair (triangles)

The two triangles have same shape (both are equilateral - like, and by visual inspection on grid, same side lengths). They are congruent.

Step4: Check congruence for fourth pair (rectangles)

The two rectangles have different side - length ratios (one is more “squarish” in proportion compared to the other), so they are not congruent.

Answer:

First pair: No, Second pair: No, Third pair: Yes, Fourth pair: No
