Honors Geometry

4. equilateral and equilangular
5. the amount each side of a figure is multiplied by when the figure is proportionally enlarged or reduced in size
7. a segment that connects the midpoints of any two sides of a triangle; every triangle has three
9. the distance around a 2-dimensional object's exterior
13. a line segment that has both endpoints on a circle
16. a rigid transformation that involves turning an entire figure about a fixed point
18. lines that intersect at a right angle with opposite reciprocal slopes
19. a figure can be rotated a certain degree about the center and will appear the same
20. a rigid transformation that involves sliding a figure to a new location

1. two-dimensional closed figure made up of straight line segments connected end-to-end. They do not intersect at any other points.
2. the number of square units needed to fill up a 2D region
3. of two events: the event in which the first event or the second event occur
6. all the outcomes in the sample space that are not in the original event
8. a rigid transformation that involves flipping a figure over the line of reflection
10. a figure can be folded on a line of symmetry where both halves of the figure will line up exactly
11. a transformation that maintains the shape of a figure but multiplies its dimensions by a chosen factor
12. functions used to try to find a side of a right triangle
14. of two events: the event in which both the first event and the second event occur
15. a point that divides a line segment into two parts of equal length
17. lie in the same plane and never intersect
