Transversal

t

intersects lines

a

and

b

. At the intersection with

a

, the angles are numbered

\angle1,\angle2,\angle3,\angle4

in clockwise order starting from the top left. At the intersection with

b

, they are numbered

\angle5,\angle6,\angle7,\angle8

in the same way. If

\angle3 = \angle6

, what can you conclude? (a)

a \perp b

(b)

t \parallel a

(c)

a \parallel b

(d) No definite relation between

a

and

b
