Question

1. name the ray in two different ways.
2. draw and label the ray.

mn

1. draw a plane containing four coplanar points a, b, c, and d, with exactly three collinear points a, b, and d.

Explanation:

Step1: Name the ray for question 8

A ray is named by its endpoint first. The ray in the first - figure can be named as $\overrightarrow{MP}$ and $\overrightarrow{NP}$ since a ray extends infinitely in one direction from its endpoint.

Step2: Draw the ray for question 9

To draw the ray $\overrightarrow{MN}$, start at point $M$ and draw a straight line passing through point $N$ and extend it infinitely in the direction of $N$. Mark the endpoint as $M$ and label the ray as $\overrightarrow{MN}$.

Step3: Draw the plane for question 10

Draw a flat surface (a plane). Place points $A$, $B$, $C$, and $D$ on the plane. Place points $A$, $B$, and $D$ on a straight - line (to make them collinear) and place point $C$ such that it is on the same plane but not on the line containing $A$, $B$, and $D$.

Answer:

1. $\overrightarrow{MP}$, $\overrightarrow{NP}$
2. Draw a ray starting at $M$ and passing through $N$ with an arrowhead indicating it extends infinitely in the direction of $N$.
3. Draw a plane with points $A$, $B$, $C$, $D$ on it where $A$, $B$, $D$ are on a straight line and $C$ is not on that line.
