basic elements of geometry
instructions: match each basic element of geometry with the correct picture.

1. $overline{cd}$
2. line ab
3. ray ab
4. $overline{cd}$
5. point p
6. line segment ab
7. plane abc
8. $overline{cd}$

Explanation:

Step1: Identify line segment $\overline{CD}$

A line - segment has two endpoints. So $\overline{CD}$ matches the picture with endpoints C and D.

Step2: Identify line AB

A line extends infinitely in both directions. The picture with arrows on both ends labeled A and B represents Line AB.

Step3: Identify ray AB

A ray has one endpoint and extends infinitely in one direction. The picture with endpoint A and an arrow pointing towards B represents Ray AB.

Step4: Another $\overline{CD}$

Same as Step 1, it matches the picture with endpoints C and D.

Step5: Identify point P

A point is a single location. The picture with just a dot labeled P represents Point P.

Step6: Identify line - segment AB

It has two endpoints A and B, so it matches the picture with endpoints A and B.

Step7: Identify plane ABC

A plane is a flat surface. The picture with three non - collinear points A, B, and C on a flat surface represents Plane ABC.

Step8: Another $\overline{CD}$

Same as Step 1 and 4, it matches the picture with endpoints C and D.

Answer:

1. Picture with endpoints C and D
2. Picture with arrows on both ends labeled A and B
3. Picture with endpoint A and arrow pointing towards B
4. Picture with endpoints C and D
5. Picture with just a dot labeled P
6. Picture with endpoints A and B
7. Picture with three non - collinear points A, B, and C on a flat surface
8. Picture with endpoints C and D
