Question

use the property to complete the statement.

transitive property of equality:

if ( mangle 1 = mangle 2 ) and ( mangle 2 = mangle 3 ), then ( mangle square = mangle square ).

Explanation:

Step1: Recall Transitive Property

The Transitive Property of Equality states that if \( a = b \) and \( b = c \), then \( a = c \).

Step2: Apply to Angle Measures

Here, \( a = m\angle1 \), \( b = m\angle2 \), and \( c = m\angle3 \). So if \( m\angle1 = m\angle2 \) and \( m\angle2 = m\angle3 \), then \( m\angle1 = m\angle3 \).

Answer:

\( m\angle\boldsymbol{1} = m\angle\boldsymbol{3} \)
