Section 1 Vocabulary
Height of Parallelogram- The perpendicular distance between the base and the opposite side
Base of Trapezoid- The trapezoids two parallel sides.
Height of Trapezoid- The perpendicular distance between the bases
Section 2 Vocabulary
Radius- The distance between the center and any point on the circle
Diameter- The distance across the circle through the center
Circumference- The distance around a circle
Circle- The set of all points in a plane that are the same distance, called the radius, from a fixed point, called the center.
Pi- The ratio of the circumference of a circle to its diameter
Section 3 Vocabulary
Polyhedron- A solid that is enclosed by polygons
Face- The polygons that form a polyhedron
Prism- A polyhedron. Prisms have two congruent bases that lie in parallel planes. The other faces are rectangles. A cube is a prism with six square faces.
Pyramid- A polyhedron. Pyramids have one base. The other faces are triangles
Cylinder- A solid with two congruent circular bases that lie in parallel planes.
Cone- A solid with one circular base
Sphere- A solid formed by all points in space that are the same distance from a fixed point called the center.
Edge- Segments where faces of a polyhedron meet
Vertex- A point where three or more edges meet
