Question

2. Use the diagram to the right to answer the questions below.

a. Name the intersection of planes JKL and HGL.
b. Name a point coplanar to points F, K, and J.
c. Are points E, J, and G coplanar? Explain.

Answer 1

a. LM

b. E

c. No.

Explanation:

a.

Two planes intersect in a line.

Here the intersecting line of the plane JKL and HGL is the line LM.

b.

As shown in the figure, the point which is coplanar to the points F, K and J is E.

c.

As per the given figure E, J and G are not in the same plane.

E and J can be lie in the same plane either EJK or EJN.

But point G is in EFG/ FGL/HGL.

Hence all the three points are not coplanar.
