∠2≅∠5

Answer to Problem 2CYU
Alternate interior
Explanation of Solution
Given information:
Figure
∠2≅∠5
Figure
In figure parallel lines are
a||b
And l||m
Alternate interior angle theorem
When two lines are cut by a transversal and alternate interior angles are congruent, then lines are parallel.
From above theorem
Then angle ∠2 of line l on transversal j and angle ∠5 of line l on transversal k are congruent angles.
Then
∠2≅∠5
Hence, ∠2≅∠5 are congruent.
