Question

quadrilateral lynu can be mapped onto quadrilateral c i k b by a rotation. if ul = 15, find kb.
answer attempt 1 out of 2
kb be determined. can cannot

Explanation:

Step1: Recall rotation property

A rotation is a rigid - motion. Rigid motions preserve distances.

Step2: Identify corresponding sides

Since quadrilateral $LYNU$ is mapped onto quadrilateral $CIKB$ by a rotation, corresponding sides are equal in length. If we assume that $UL$ and $KB$ are corresponding sides (the problem should clarify the correspondence, but based on the nature of rigid - motions), then $KB = UL$.

Answer:

$KB = 15$
