Geometry Chapter 8

2. a polygon with three corners and three sides
3. a statement formed by switching the hypothesis and conclusion of an original conditional statement, then negating both parts
8. the measurement of the distance between two points on a line segment
10. the relationship between two or more geometric figures where the ratios of their corresponding sides are equal
12. The total length to the outside of a figure
13. a way to compare two quantities by dividing one by the other
14. Same thing in a different spot
15. three pairs of corresponding sides of two triangles are proportional
18. transformation that takes a figure and creates a new figure that is the same shape but potentially a different size

1. two figures that have the same shape but may be different sizes
4. To divide into two equal parts
5. lines that are always the same distance apart and that never meet
6. a line, ray, or line segment that intersects other lines, rays, or line segments on a plane at different intersecting points
7. a statement that two ratios are equal
9. The total space on the inside of a figure
11. a closed two-dimensional figure composed of straight-line segments that meet at their endpoints
15. two sides of one triangle are proportional with two sides of another triangle, and the included angles in both triangles are congruent
16. the measure of how steep a line is, calculated as the ratio of the rise divided by run between two points on that line
17. two triangles with two pairs of corresponding angles that are congruent
