Pls i will mark brainliest to correct and explain !
(two questions)
which relationship is always true for the angles r, x, y, and z of triangle abc? (first picture)
x + z = y

180 degrees − x = r

x + y + z = 180 degrees

x + y + z = 90 degrees

the figure shows two parallel lines ab and de cut by the transversals ae and bd: (second picture)

which statement best explains the relationship between triangle abc and triangle edc ?

triangle abc is similar to triangle edc , because m∠3 = m∠6 and m∠1 = m∠4

triangle abc is similar to triangle edc , because m∠3 = m∠4 and m∠1 = m∠5

triangle abc is congruent to triangle edc , because m∠3 = m∠4 and m∠1 = m∠5

triangle abc is congruent to triangle edc, because m∠3 = m∠6 and m∠61 = m∠4
