-Line (segment)  a line is a straight path that has no thickness and does not extend forever.

-Plane  a flat surface that has no thickness and extends forever.

-Angle  A figure formed by two rays with a common endpoint.

-perpendicular lines  Intersecting lines to form 90 degree angles.

-parallel lines  Lines in the same plane that don’t 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 for right angles.

-Rectangle  A quadrilateral with four right angles.

-trapezoid  A quadrilateral with exactly one pair of parallel sides.

-parallelogram  Quadrilateral with two pairs of parallel sides.

-circle  The set of points in a plane that are a fixed distance from a given point called the center of a circle.

-cylinder  A three-dimensional figure with two parallel congruent circular bases and a curved lateral surface that connects the bases.

-sphere  The set of points in a space that are a fixed distance from a given point called the center of the sphere.

-pyramid  A polyhedron formed by a polygonal base and triangular lateral faces that meet at a common vertex.
