Across
- 3. the point on a line segment or coordinate plane that divides a segment into two congruent segments.
- 4. The sum of the areas of the faces of a geometric solid. How much it takes to cover it.
- 9. points where 3 or more polygons(faces) meet.
- 10. 3 or more points that are on the same line.
- 11. To cut an angle or line segment in half.
- 13. Two adjacent angles that create a line.
- 15. A closed figure whose sides are 3 or more line segments connected at their endpoints.
- 17. points, lines, segments, and rays that are on the same plane
- 18. a theorem that for all right triangles (leg₁)² + (leg₂)² = (hypotenuse)² (a²+b²=c²)
- 20. a transformation that flips a figure over a line.
- 21. The space a solid shape takes up, measured in cubic units. What it takes to fill it up.
- 22. Two angles whose sum = 90⁰
- 23. segments where the polygons(faces) meet.
Down
- 1. Two angles whose sum = 180⁰
- 2. the figure AFTER you move it in a transformation.
- 5. A polygon with each interior angle having a measure less than 180°- no dents.
- 6. having the same size or measurement:≅
- 7. angles that are formed by two intersecting lines but are NOT adjacent
- 8. polygons that make up the sides of the polyhedron.
- 12. a transformation that slides a figure on the coordinate plane.
- 14. A polygon in which at least one of the interior angles has a measure of more than 180 degrees. It has a dent (cave) in it.
- 15. The distance around the polygon. Add all the sides up.
- 16. a transformation that spins a figure around a fixed point
- 18. A solid (3-D figure) that is formed by polygons.
- 19. The figure BEFORE you move it in a transformation.
