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

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.
