Answer:
5
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
pairs 1 and 3
Explanation:
Congruent figures are the same size and the same shape.
Pair 1 has two polygons that are the same size and same shape; they are congruent.
Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.
Pair 3 has two polygons that are the same size and same shape; they are congruent.
Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.
