Geometry

4. a point on one end, and it extends infinitely in the other direction.
5. Bisector- a ray that cuts the angle exactly in half, making two equal angles.
10. diagram- uses circles to represent relationships among sets of objects
11. a right triangle is the side of the triangle that is opposite to the right angle.
15. triangle- a triangle with all three sides unequal.
16. a cube has six
17. a segment connecting any vertex of a triangle to the midpoint of the opposite side.
18. the point where two sides of a polygon meet.
19. lines- two lines in the same plane that never intersect.

1. Triangle- a triangle with all three angles less than 90
2. is a polygon with exactly four sides.
3. is a segment that passes through the center and has its endpoints on the circle.
6. segment- s the portion of a line lying strictly between two points. It has a finite length and no width.
7. corresponding lengths are the same, and if all corresponding angles have the same measure.
8. theorem- states that if you have a right triangle, then the square built on the hypotenuse is equal to the sum of the squares built on the other two sides. a2 + b2 = c2.
9. a quadrilateral that has one pair of opposite sides that are parallel.
12. triangle-is a triangle with three equal sides.
13. a regular quadrilateral.
14. Angle- an angle with its vertex at the center of a circle.
20. has only one dimension
