Which set of equations is enough information to prove that lines c and d are parallel lines cut by transversal p?
a. m∠1 = 81° and m∠2 = 99°
b. m∠3 = 99° and m∠4 = 99°
c. m∠2 = 99° and m∠4 = 99°
d. m∠4 = 81° and m∠1 = 81°

we know that

if c and d are parallel lines

then

m∠2=m∠4 > by alternate exterior angles

m∠2=m∠3 > by corresponding angles

therefore

the answer is the option C

m∠2 = 99° and m∠4 = 99°

explanation:

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
