name finley date chapter 1 words to know • concepts basic geometric concepts complete the sentences with words from the box. plane line ray congruent line - segments bisector theorem collinear points 1. a geometric figure that extends endlessly in two directions is a 2. a flat surface that extends endlessly in all directions is a 3. points on the same line are 4. a part of a line with one endpoint is called a 5. a statement that can be proved is called a 6. a is a line that intersects a line - segment at its mid - point. 7. line segments that have the same length are write true or false next to each sentence. if the sentence is false, replace the underlined word to make it true. 8. a line is made up of infinitely many points and extends endlessly in two directions. 9. a bisector is a point that divides a line segment into two congruent parts 10. a postulate is a statement that is accepted with proof.

Explanation:

1. A line extends infinitely in two directions.
2. A plane is a flat - surface extending infinitely in all directions.
3. Collinear points are on the same line.
4. A ray has one endpoint and is part of a line.
5. A theorem is a provable statement.
6. A bisector intersects a line - segment at its mid - point.
7. Congruent line segments have the same length.
8. True. A line is made up of infinitely many points and extends infinitely in two directions.
9. False. A bisector is a line (not a point) that divides a line segment into two congruent parts.
10. False. A postulate is a statement that is accepted without proof.

Answer:

1. line
2. plane
3. collinear points
4. ray
5. theorem
6. bisector
7. congruent line segments
8. True
9. False, change "point" to "line"
10. False, change "with" to "without"
