Point• It names a location and has no size.

Line (segment)• A line is a straight path that has no thickness

and it connects two points.

Plane• A flat surface that has no thickness and

extends forever.

Angle• A figure formed by two rays with a common

endpoint.

Perpendicular Lines• Two intersecting lines that form 90 angles

Parallel Lines• Lines in the same plane that do not intersect

Triangle• A three-sided polygon

Right Triangle• A triangle with one right angle

Pentagon• A five-sided polygon

Hexagon• A six-sided polygon

Square• A quadrilateral with four congruent sides and

four right angles

Rectangle• A quadrilateral with four right angles

Trapezoid• A quadrilateral with exactly one pair of parallel

sides

Parallelogram• A quadrilateral with two pairs of parallel sides

Circle• A closed plane curve consisting of all points at

a given distance from a point within it

Cylinder• A three-dimensional surface or solid object

bounded by a curved surface and two parallel circles of equal size at each end

Sphere• The set of points in a shape that are a fixed

distance from a given point called the center of the sphere

Cube • A prism with six square faces

Octagon• An eight-sided polygon

Intersecting lines• Two lines that share one common point
