Question

1. which statement is not true based on the figures below? o ae≅jn o ab≅kj o de≅mn o cd≅jk

Explanation:

Step1: Observe the congruence markings

In the given polygons, the number of red - hash marks on each side indicates congruence. Sides with the same number of hash marks are congruent.

Step2: Analyze each option

• For $AE\cong JN$, $AE$ has one hash - mark and $JN$ has one hash - mark, so they are congruent.
• For $AB\cong KJ$, $AB$ has two hash - marks and $KJ$ has two hash - marks, so they are congruent.
• For $DE\cong MN$, $DE$ has three hash - marks and $MN$ has three hash - marks, so they are congruent.
• For $CD\cong JK$, $CD$ has three hash - marks and $JK$ has two hash - marks, so they are not congruent.

Answer:

$CD\cong JK$ is not true.
