PLS HELP I WILL MARK BRAINLIEST TO CORRECT AND EXPLAIN ANSWERS!!!!!!!!!!!!!!!!!!!(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 degreesThe 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
