• Point
• An undefined term in geometry, it names a location and has no size.
• Line (Segment)
• A part of a line that is bounded by two end points, and contains every point on the line between its end points.
• 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
• Lines that intersect at 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
• The set of points in a plane that are a fixed distance from a given point called the center of the 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 space that are a fixed distance from a given point called the center of the sphere.
• Octagon
• An eight-sided polygon.
• Cube
• A prism with six square faces.
• Hemisphere
• Half of a sphere.
