Question

For the following figure, complete the statement for the specified points.

Points R, T, and B are _____.


1) collinear
2) coplanar
3) both collinear and coplanar
$) neither collinear nor coplanar

Answer 1

3 because they lay on the same line and the same plane making them coplanar and collinear. 

Answer 2

Points R, T, and B are:

3) both Collinear and Coplanar.

Explanation:

Collinear points--

Two or more points are said to be collinear if they lie on the same line.

Coplanar points--

The set of points are said to be coplanar if they lie on the same plane.

Also, we know that a line always lie on a plane and hence the points which are on the line also lie on the same plane.

i.e. the set of points which lie on one line are always coplanar.

i.e. Collinear points are always Coplanar.

Here the Points R, T and B are on the same line and hence they are collinear and hence coplanar.
