Question

1. use the diagram to the right to name the following. a) three coplanar points. yvw or zyv or zvw or zwx or zyx b) a plane containing point x. plane r c) the intersection of plane r and plane zvy. line vy d) how many planes appear in the figure? 5 e) how many planes contain point w? 3

Explanation:

Step1: Identify coplanar points

Coplanar points lie on the same plane. Looking at the figure, points Y, V, W, Z are coplanar. So for part a), the answer is based on observing these coplanar - point combinations.

Step2: Locate point X

For part b), we find all planes that contain point X. Plane R is one such plane.

Step3: Determine plane intersection

For part c), we look at the intersection of plane R and plane ZVY. The intersection is the line segment VY.

Step4: Count planes in the figure

For part d), by observing the figure, we can count 5 planes.

Step5: Locate point W

For part e), we count the planes that contain point W. There are 3 such planes.

Answer:

a) YVW or ZVW or ZWY or ZWX or ZYX
b) Plane R
c) Line VY
d) 5
e) 3
