2. Point Point -somethingthat has position but not extension, as the intersection of two lines. 3.
- Line - a part cut off from a figure, esp. a circular or spherical one, by a line or plane, as a part of a circular area contained by an arc and its chord or by two parallel lines or planes.
Line(Segment) 4. Plane
- Plane - a surface generated by a straight line moving at a constant velocity with respect to a fixed point.
- Angle - the space within two lines or three or more planes diverging from a common point, or within two planes diverging from a common line.
6. Perpendicular Lines Perpendicular Line - meeting of a given line at right angles. 7. Parallel Lines
- Parallel Lines - lying in the same plane but never meeting no matter how far extended.
- Triangle - a closed plane figure having three sides and three angles
9. Right Triangle
- Right Triangle - a triangle having a right angle
- Pentagon - a polygon having five angles and five sides
- Hexagon - a polygon having six angles and six sides
- Square - a rectangle having all four sides of equal length
- Rectangle - a parallelogram having four right angles
- Trapezoid - a quadrilateral plane figure having two parallel and two nonparallel sides.
- Parallelogram - a quadrilateral having both pairs of opposite sides parallel to each other.
- Circle - a closed plane curve consisting of all points at a given distance from a point within it called the center
- Cylinder - a surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.
- Sphere - a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center.
19. Triangular Prism
- Triangular Prism - a prism whose bases are triangles
- Crescent - a shape resembling a segment of a ring tapering to points at the ends
