Point A point is something that has a
position but takes up no space or volume. It usually defines a line segment’s endpoints or a positions on a plane.
Line Segment
A line segment is a broken part of a line with two endpoints
Plane
A plane is a flat surface created by at least three or more points. When 3 points make a plane they are coplanar.
Angle
An angle occurs when two rays with the same endpoint jut out in different directions.
Perpendicular Lines
Perpendicular Lines are two lines that intersect at a 90 degree angle.
Triangle
A triangle is a closed figure with three sides and three angles.
Right Triangle
A right triangle is a triangle with a 90 degree angle.
Pentagon
A closed figure with five sides and five angles
Hexagon
A closed figure with six sides and six angles
Square
A square is a closed figure with four equal sides and four equal angles.
Rectangle
A rectangle is a four sided figure with two pairs of two equal sides, and four equal angles
Trapezoid
A quadrilateral figure with two parallel sides and two sides that are not parallel.
Parallelogram
A quadrilateral with two pairs of parallel lines and two pairs of congruent angles
Circle
A circle is a closed plane curve consisting of all the points in a set distance
Cylinder
A cylinder is a three dimensional figure with two circles as a base
Sphere
A sphere is a three dimensional figure created by the revolution of a semicircle rotated 360 degrees about its axis.
Triangular Prism
A triangular prism is a three dimensional figure with tow triangles for bases
Vertex
A vertex is a point that connects two or more lines that make a shape or figure.
Line
A line is a flat extension that has no width an goes on forever in both directions
