Point-A precise location or place on a plane.

Line Segment-straight line which links two points without extending beyond them.

Plane-An imaginary flat surface that is infinitely large and with zero thickness

Angle-formed by two lines or rays diverging from a common point

Perpendicular lines-A line that crosses at a right angle

Parallel lines-Lines that are always the same distance apart and will never meet.

Triangle-A closed figure consisting of three line segments linked end-to-end

Right Triangle-A triangle where one of its interior angles is a right angle

Pentagon-A polygon with 5 sides

Hexagon-A polygon with 6 sides

Square-A 4-sided regular polygon with all sides equal and all internal angles 90°

Rectangle-A 4-sided polygon where all interior angles are 90°

Trapezoid-A quadrilateral which has at least one pair of parallel sides 

Parallelogram-A quadrilateral with opposite parallel lines

Circle-A line forming a closed loop, every point on which is a fixed distance from a center point.

Cylinder-A surface generated by a straight line moving parallel to a fixed straight line and intersecting a plane curve.

Sphere-A three-dimensional surface, all points of which are equidistant from a fixed point.

Octagon-A polygon with 8 sides

Oval-any curve that looks like an egg or an ellipse. 

Rectangular Prism- object which has six faces that are rectangles.
