Question

9. What are two other ways to name the plane C?

Answer 1

Answer with explanation:

→→→A Surface is said to be plane if you take any two points on the surface and the line joining these two points , completely lie on the surface.

→→Three Points are said to be Collinear , if they lie on a line.

→Points are said to be Coplanar , if they lie on the same plane.

1. The plane C can be named in two other ways

(a) Plane B, (b) Plane G

2. The three Collinear Points are:

 E, B and F

3. Four Coplanar points are:

 E, B, F and G.

Answer 2

Other names for plane C can be plane EFG or plane EBF since planes can be named using three points that lie on the plane. The three collinear points or the three points that lie on the same line are points E,B, and F which lie on line n. And, the four coplanar points or the points that lie on the same plane are points B,E,F, and G.
