Question

question
in $\triangle qrs$, $\overline{sq}\cong\overline{rs}$ and $m\angle r = 21^{\circ}$. find $m\angle q$.
answer attempt 1 out of 2
submit answer

Explanation:

Step1: Identify the triangle type

Since \( \overline{SQ}\cong\overline{RS}\), \(\triangle QRS\) is an isosceles triangle. In an isosceles triangle, the base - angles are equal. So, \(m\angle Q=m\angle R\).

Step2: Substitute the given value

Given \(m\angle R = 21^{\circ}\).

Answer:

\(21^{\circ}\)
