Geometry Definitions

3. is a segment that connects two points on the circle
5. is a polyhedron with two congruent polygonal bases lying in parallel planes and lateral faces that are parallelograms
6. three or more sided objet that is enclosed and coplanar
9. is the set of points in a plane that are a given distance from a given point in the plane
10. two ratios set equal to each other where the product of the means are equal to the product of the extremes
11. a point that splits a segment into two congruent segments
12. 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
13. is the altitude for a lateral face of a pyramid(cone)
14. is a quadrilateral with two pairs of adjacent side congruent but opposite sides are not congruent and not parallel
15. is a line that intersects two or more coplanar lines at different points
17. three noncollinear points and the segments that connect the points
18. is the point where the edges intersect
19. is the angle by which you must lower your line of sight in regards to the horizontal
20. comparison of two numbers with the same units by division
21. is a line that intersects a circle at two points

1. 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
2. is a parallelogram with four congruent sides
4. objects with the same shape but not necessarily the same size
7. is a segment that connects the midpoints of any two sides of a triangle
8. is a segment that connects the vertex of a triangle to the midpoint on the opposite side of the vertex
16. 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
