Across
- 4. is the point where the edges intersect
- 5. three noncollinear points and the segments that connect the points
- 7. is a quadrilateral with two pairs of adjacent side congruent but opposite sides are not congruent and not parallel
- 9. is a segment that connects two points on the circle
- 10. is the set of points in a plane that are a given distance from a given point in the plane
- 11. is a segment that connects the midpoints of any two sides of a triangle
- 15. is the point of concurrency for the medians, it is 2/3 away from the vertices and is the center of gravity for the object
- 17. is a polyhedron with two congruent polygonal bases lying in parallel planes and lateral faces that are parallelograms
- 18. goes from the vertex of the intersection of all the lateral faces to the base and is perpendicular. For a right pyramid it will also intersect the base polygon at its center
- 19. comparison of two numbers with the same units by division
- 20. is a line that intersects a circle at two points
Down
- 1. is a segment that connects the vertex of a triangle to the midpoint on the opposite side of the vertex
- 2. is the angle by which you must lower your line of sight in regards to the horizontal
- 3. is a line, ray, or a segment that splits a segment into two congruent segments and forms four right angles at the point of intersection
- 6. is a parallelogram with four congruent sides
- 8. two ratios set equal to each other where the product of the means are equal to the product of the extremes
- 12. is the altitude for a lateral face of a pyramid(cone)
- 13. is a line that intersects two or more coplanar lines at different points
- 14. a point that splits a segment into two congruent segments
- 16. objects with the same shape but not necessarily the same size
