Geometry Final

4. Can be used to find the distance between two points. The equation is d=√((x_2-x_1)²+(y_2-y_1)²).
6. A quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. Properties include two pairs of consecutive and congruent sides, non-vertex angles, and perpendicular diagonals.
7. A general term for four specific ways to manipulate a shape and/or position of a point. This keeps the shape the same size, area, angles, and line lengths.
9. A quadrilateral with at least one pair of parallel sides. Properties include bases that are parallel to each other and the median is parallel to both the bases.
13. Coplanar straight lines that do not intersect at any point. Both of these lines have the same slope.
16. A quadrilateral with four right angles. Properties include the opposite sides are parallel and equal to each other.
17. A rate for one of something. Example: 70 yards in 10 seconds is the same as 7 yards in 1 second.
19. A polygon that is equiangular and equilateral. Properties include equal-length sides with equal angles between each side.
20. Same Shape and size. Example: Triangle A = Triangle B.

1. A quadrilateral with both pairs of opposite sides. Properties include if one angle is right then all angles are right and the diagonals bisect each other.
2. Two lines that meet or intersect each other. These lines form a right angle.
3. All angles are the same. A,B,and C are 60 degrees.
5. A triangle in which all three sides have the same length. Example: A=B=C.
8. The point of intersection of all the three interior angle bisectors of the triangle. also known as the center of a triangle's circle.
10. The point at which the perpendicular bisectors of the sides of a triangle intersect. Is also equidistant from the three vertices.
11. One side of a triangle. A trapezoid has two of these that can be isosceles.
12. A quadrilateral with both pairs of opposite sides parallel and all sides the same length. Properties include opposite angles are congruent, the diagonals intersect each other at 90 degrees, the diagonals bisect the opposite interior angles, and the adjacent angles are supplementary.
14. The angle between a side of a polygon and an extended adjacent side. Example: An angle formed by a transversal as it cuts one of two lines and is situated on the outside of the line.
15. Is a mirrored image across the axis. Also described as flipped over a line.
18. Two amounts showing the number of times one value contains or is contained within the other. Example: 8 to 1 and 8/1.
