Answer:
See below for answer.
Step-by-step explanation:
m ∠3 = m∠ 7 If ║ then cor. ∠s are =
m ∠2 = m∠7 Transitive ∠2 = ∠3; ∠3 = ∠7; ∴∠2 = ∠7
The missing reason is : transitive property.
What is Transitive property?
A transitive relation is defined as a homogeneous relation R over the set A, where the set contains the elements such as x, y and z, such that R relates x to y and y to z, then R also relates x to z.
As in statement 3 we have,
∠2 = ∠3
and in statement 5 we also have
∠3 = ∠7
So, by using transitive property we can write,
If a = b and b = c,
then a = c
Hence, m∠2 = m∠7 using transitive property.
