Explanation:
These two similar quadrilaterals could look like this:
We have to follow the same order of the letters for each vertex. We can see that the corresponding vertices are :
• R - J
,• S - K
,• T - L
,• U -M
This means that their angles are congruent (the symbol you wrote means congruent)
We can see in the options that the only one that doesn't match what I wrote above is option C, because U and J are not corresponding vertices, so their angles are not congruent.
Answer:
The option that's NOT true is option C.
