Question

lines q and f intersect at point z in plane u.
a)
diagram of two lines intersecting at point e in plane u

b)
diagram of two parallel lines in plane u

c)
diagram of two lines intersecting at point z in plane u

Explanation:

Step1: Analyze the condition

We need to find the diagram where lines \( d \) and \( f \) intersect at point \( Z \) in plane \( U \).

Step2: Check each option

• Option A: The intersection point is \( F \), not \( Z \), and there is a line \( z \) which is not relevant. So A is incorrect.
• Option B: Lines \( d \) and \( f \) are parallel, not intersecting. So B is incorrect.
• Option C: Lines \( d \) and \( f \) intersect at point \( Z \) in plane \( U \), which matches the given condition.

Answer:

C) The diagram with lines \( d \) and \( f \) intersecting at point \( Z \) in plane \( U \) (the left - most diagram among the three)
