Question

which pairs of figures below are congruent? congruent? yes no congruent? yes no congruent? yes no

Explanation:

Step1: Recall congruent - figure definition

Two figures are congruent if they have the same shape and size.

Step2: Analyze first - pair of triangles

The first pair of triangles have different shapes (one is equilateral - like and the other is a right - triangle), so they are not congruent.

Step3: Analyze second - pair of shapes

The second pair of shapes have different shapes and sizes, so they are not congruent.

Step4: Analyze third - pair of rectangles

The third pair of rectangles have different sizes (one is a long and thin rectangle and the other is a more square - like rectangle), so they are not congruent.

Step5: Analyze fourth - pair of circles

The fourth pair of circles have the same shape (circular) and size, so they are congruent.

Answer:

The fourth pair (the two circles): Yes; The first pair (the two triangles): No; The second pair (the two non - standard shapes): No; The third pair (the two rectangles): No
