Question

completing statements in exercises 10-14, use the property to complete the statement. 10. symmetric property of equality: if (mangle a = mangle b), then ?.

Explanation:

Step1: Recall symmetric property

The symmetric property of equality states that if \(a = b\), then \(b=a\).

Step2: Apply to angle - measure

Given \(m\angle A=m\angle B\), by the symmetric property of equality, we have \(m\angle B = m\angle A\).

Answer:

\(m\angle B=m\angle A\)
