Question

1. complete the rule for the reflection of quadrilateral abcd across line m.

$r_{m}(abcd)\to$

Explanation:

Step1: Recall reflection property

A reflection across a line \(m\) maps each point of the original figure to its mirror - image across line \(m\). For a quadrilateral \(ABCD\), its reflection \(r_m(ABCD)\) will map it to a new quadrilateral \(A'B'C'D'\).

Answer:

\(r_m(ABCD)\to A'B'C'D'\)
