Question

∠p and ∠r are the pairs of alternate angles formed by two parallel lines and its transversal. If m∠ p = 80° then m∠ r = ? a) 80° b) 120° c) 100° d) 90°​

Answer 1

Answer:

angle p = angle r

let the alternative angle be x

triangle are all sides are equal,

m angle p= 80°

180° are triangle agnles

= 180°- 80°= 100°
