Question

1. given: $\frac{1}{2}mangle abc=\frac{1}{2}mangle nmv$ (13) prove: $mangle abc = mangle nmv$ a. multiplication property b. definition of a segment bisector c. substitution property d. addition property e. definition of the midpoint of a line segment

Explanation:

Step1: Multiply both sides by 2

$2\times\frac{1}{2}m\angle ABC = 2\times\frac{1}{2}m\angle NMV$

Step2: Simplify

$m\angle ABC = m\angle NMV$

Answer:

A. Multiplication Property
