Plane
An undefined term in geometry, it is a flat surface that has no thickness and extends forever.
Angle
A figure formed by two rays with a common endpoint.
Perpendicular Lines

Parallel Lines
Lines in the same plane that do not intersect.
Right Triangle

Parallelogram
A quadrilateral with two pairs of parallel sides.
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.
Cone
