In the adjoining figure, name 3 non-collinear points

We need to write the name of 3 non--collinear points. When the points in a place, do not lie on the same line, then such points are called non-collinear points. Therefore, the non collinear points are: (i) C , E and F (ii) A , C and D (iii) A , B and D (iv) C , D and F

In the adjoining figure, name 3 concurrent lines

We need to write the name of the concurrent line in the figure. Concurrent lines are the lines, in 2-D geometry, which intersect each other exactly at one point. Therefore, the 3 concurrent lines are: l , n and q also m , o and q

The adjacent figure represents a cuboid. Now answer the following questions. Name the plane parallel to A B C D .

We need to write the name of the plane parallel to A B C D . Parallel planes are planes in the same three-dimensional space that never meet. Therefore, the plane parallel to A B C D is E F G H

The adjacent figure represents a cuboid. Now answer the following questions. Name the plane parallel to B C G F .

We need to write the name of the plane parallel to B C G F . Parallel planes are planes in the same three-dimensional space that never meet. Therefore, the plane parallel to B C G F is A D H E

The adjacent figure represents a cuboid. Now answer the following questions. Name any one plane intersecting A B F E .

We need to write the name of the plane intersecting A B F E . Intersecting planes are planes that intersect along a line. Therefore, the plane intersecting A B F E are: (i) A B C D (ii) E F G H (iii) A D H E (iv) B F G C
