Q15 - Geometry

Question

A plane can be named by three or more non-collinear points it contains. In chapter 12 you will study pyramids like the one shown at the right below.

Name three lines that intersect at point R.

Step-by-Step Solution

Answer

The three lines that intersect at point R are RW, RS, and RV.

Step 1. Observe the given diagram.

The given diagram is of a pyramid which is made up of five planes.

Step 2. Observe the figure shown below.

The lines that intersect are highlighted in the below diagram.

Step 3. Name the lines passing through the point R.

From the above figure, it can be noticed that:

The first line passing through point R is RW.

The second line passing through the point R is RS.

The third line passing through the point R is RV.

 

Therefore, three lines that intersect at R are RW, RS, and RV.
