Question

use tools draw and label a figure for each relationship. 20. points x and y lie on $overleftrightarrow{cd}$. 21. two planes do not intersect. 22. line $m$ intersects plane $r$ at a single point. 23. three lines intersect at point $j$ but do not all lie in the same plane. 24. points $a(2,3), b(2, - 3), c$, and $d$ are collinear, but $a,b,c,d$, and $f$ are not.

Explanation:

Step1: Draw for 20

Draw a line $\overleftrightarrow{CD}$. Mark two points $X$ and $Y$ on it.

Step2: Draw for 21

Draw two parallel planes to show they do not intersect.

Step3: Draw for 22

Draw a plane $R$ and a line $m$ that touches the plane at one point.

Step4: Draw for 23

Draw three lines that meet at point $J$ such that they are not coplanar.

Step5: Draw for 24

Draw a line and mark points $A(2,3)$ and $B(2, - 3)$ on it. Mark points $C$ and $D$ also on the same line. Mark a point $F$ outside this line.

Answer:

Figures are drawn as described above for each relationship.
