Point

• An undefined term in geometry, it names a location and has no size.

Line (Segment)

• An undefined term in geometry, a line is in a straight path that has no thickness and extends forever.

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.

His right arm is almost at 90°.

Perpendicular Lines

• Intersecting lines that form 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.

Cone

• A three-dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex.

Pyramid

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

Octagon

• An eight-sided polygon.
