Property used:
a. The Transitive Property of Congruence states that if two angles are each congruent to a third angle, then they are congruent to each other.
b. The Additive Property of Equality states that if same number is added to both sides of the equation then the sides of the equation remains equal.
c. If the measure of two angles is equal then the angles are known as congruent angles.
d. According to Substitution Property, if
Approach:
The first statement of the proof is given. That is.
It means the angles
The second statement of the proof is given. That is.
It means that the two angles are congruent then the measures of those angles will be same so, the reason for the second statement is “If two
The third statement of the proof is given. That is.
And,
In the third statement
