In the figure, line l1 is parallel to line l2. if the measure of ∠7 = 42°, what is the measure of ∠3 and why?

a. 42°, corresponding angles are congruent
b. 42°, same side exterior angles are congruent
c. 42°, alternating interior angles are congruent
d. 18°, corresponding angles are supplementary

don't put wrong answer!

The answer is A because angle 7 and angle 3 are corresponding angles :)

A because the angles are corresponding, which means they are congruent.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
