Given: ∠5 ≅ ∠13
which lines must be parallel?
a) r and s
b) p and q
c) p and r
d) q and s

Option A) r and s

Step-by-step explanation:

we know that

When two lines are crossed by another line (called the Transversal), the angles in matching corners are called Corresponding Angles. If the lines are parallel, then the angles are congruent

In this problem

If lines r and s are parallel

then

m∠5≅m∠13 > by corresponding angles

Step-by-step explanation: because i did this in 9th grade before they do it in all grades.
