(a) There are two sets of parallel lines passing through a plane. A transversal cuts the two sets of lines. Find the number of distinct points of intersection.
(b) The following diagram shows parallel lines cut by a transversal. Find x. [3 MARKS]
(a) Solution: 1 Mark
(b) Application of concept: 1 Mark
Correct Answer: 1 Mark
(a) There are 4 points of intersection between the parallel lines & transversal.
(b) In the above figure since the two lines are parallel and cut by a transversal, using the property of corresponding angles:
=> 2x - 60∘ = x
=> x - 60∘ = 0
=> x = 60∘
