Complete the paragraph proof to prove the statement.
given: ∠abc ≅ ∠def and ∠ghi ≅ ∠def
prove: m∠abc = m∠ghi
we are given that angle abc and are congruent, and that angle ghi and angle def are congruent. by the , the measure of angle abc is equal to the measure of angle def, and the measure of angle ghi is equal to the measure of angle def. by the substitution property, the measure of angle abc is equal to .

Two angles are said to be congruent if they have the same measure. The measure of angle ABC is congruent to the measure of angle DEF i.e.

To prove that:

We have:

and

is common in the above equations.

This means that we can use substitution property

Substitution property states that:

If and then:

Using the above as a reference,

The equations can be combined as:

just finished completed it on Ed

it has the same slope and a different y-intercept

hope this : )

i dont get the question
