Question

according to the passage, which of the following is not true? a paper cutouts can be used to determine congruence. b congruent figures have exactly the same size and shape. c congruence only happens in three - or four - sided figures. d two octagons can be congruent if their corresponding sides and angles match up.

Explanation:

Congruence is a property applicable to all polygons, not just three - or four - sided figures. If two polygons have corresponding sides and angles equal, they are congruent regardless of the number of sides. For example, two octagons can be congruent if their corresponding parts match. Paper cutouts can be used to check congruence by superimposing them. Congruent figures have the same size and shape by definition.

Answer:

C. Congruence only happens in three - or four - sided figures.
