Geometry

4. An angle w/ a degree measure of 90 degrees. This angle is always in the corner of a square.
6. They are interior angles, non-adjacent, and on are on opposite sides of the transversal. It's an angle formed by a transversal.
7. 2 adjacent angles that are supplementary. Together, they form a straight line.
11. Formed by 2 rays w/ a common endpoint. 4 main types of this.
12. 4 right angles and 4 congruent sides. Diagonals are perpendicular.
14. A flat surface made up of points. Named by 3 non-collinear points.
15. A quadrilateral and its diagonals bisect opposite angles. All sides are congruent.
16. A quadrilateral that has 2 pairs of consecutive congruent sides. It also has one pair of opposite angles that are congruent and diagonals are perpendicular.
17. A location that has no size or shape. Uses a capital letter to name it.
19. An equation that states 2 ratios are equal. Written was a/b = c/d.

1. 2 angles next to each other. They share a common side.
2. They have the same shape and size. Angles and sides are congruent.
3. A quadrilateral in which both pairs of opposite sides are parallel. Consecutive angles are supplementary.
5. It's made up of points w/ no thickness or width. Named by a lower case letter.
8. A quadrilateral w/ only 1 pair of opposite sides being parallel. Also, consecutive angles between parallel lines are supplementary.
9. A quadrilateral where diagonals are congruent. 4 right angles.
10. A comparison of 3 or more quantities. It can be written as a:b:c.
13. A comparison of 2 quantities. It can be simplified or reduced.
18. A closed figure formed by 3 or more line segments called sides. An example of this would be a triangle.
