# In Fig, l, m and n are parallel lines intersected by transversal p at X, Y and Z respectively. Find ∠1, ∠2 and∠3.

Answer :

From the given figure,

3 + y = 180o(Linear pair)

3 = 60o

Now,

Line l m

1 = 3 (Corresponding angles)

1 = 60o

Now, m n

2 = 120o(Alternate interior angle)

Therefore,

1 = 3 = 60o

2 = 120o
