4. PLANE
An undefined term though of as a flat surface that extends indefinitely along it’s edges.

5. COLLINEAR
On the same line.

6. COLLINEAR

7. COPLANAR
On the same plane.

8. LINE SEGMENT
Two points and all the points between them that are collinear with the two points.

9. END POINTS
The point at either end of a segment or an arc, or the first point of a ray.

10. CONGRUENT
Identical in shape and size.

11. BISECTS
To divide into two congruent parts.

12. RAY
A point on a line, and all the points of the line that lie on one side of this point.

16. 6. Notes H B D A
You wanna say that two segments are congruent, you mark it in with cut marks. You wanna KEEP saying that segments are congruent, you keep on marking it up. C G F

17. 7. Classwork
Write down every congruency statement. H B D A C G F

18. 8. Notes
Midpoint: The point on a segment that’s the same distance from both endpoints.
D is the midpoint of BC
H is the midpoint of FD
A is the midpoint of DE
