Question

1. use the diagram to the right to name the following

a) three coplanar points.
b) a plane containing point x.
c) the intersection of plane r and plane zh.
d) how many planes appear in the figure?
e) how many planes contain point h?

Explanation:

Step1: Recall collinear points definition

Collinear points lie on the same line. Let's assume points on a line in the diagram (for example, if there are points on a straight - line segment in the figure like points A, B, C on a line).

Step2: Identify a plane with point X

A plane is a flat surface that extends infinitely. If point X is in the figure, a plane could be the base plane or one of the side - planes that contains X.

Step3: Determine intersection of planes

The intersection of two planes is a line. We look for the common line where plane R and plane ZY meet.

Step4: Count planes in the figure

We count all the flat surfaces that extend infinitely in the figure, including base and side - planes.

Step5: Find planes with point W

We check which flat surfaces pass through point W.

Answer:

a) (Provide three collinear points based on the figure, e.g., if there are points on a line: Points A, B, C)
b) (Name a plane that contains point X, e.g., Plane ABC if X is on that plane)
c) (Name the line of intersection of plane R and plane ZY, e.g., Line AB)
d) (Count and state the number of planes in the figure, e.g., 5)
e) (Count and state the number of planes that contain point W, e.g., 3)
