Using the given figure, let's answer the following questions.
• (a). Name the plane in 3 different ways.
The plane can be said to be the name of the figure.
We can name the plane using any 3 points on the plane.
To name the plane, we have:
Name 1: Plane e
Name 2: Plane CMB
Name 3: Plane CED
• (b),. Identify two coplanar lines.
Coplanar lines are lines which lie in the same plane.
From the figure, two coplanar lines are:
Line ME and Line BD
• (c). Identify two non-coplanar lines.
Non-coplanar lines are lines which do not lie on the same plane.
From the given figure, we can see that all lines are in the plane.
Therefore, there are no non-coplanar lines.
ANSWER:
• (a). Plane e
Plane CMB
Plane CED
• (b). Line ME
Line BD
• (c). No non-coplanar lines
