# CHAPTER 10

## Vocabulary

Base of a parallelogram is the length of any side of the parallelogram can be used as the base.

Height of a parallelogram is the perpendicular distance between the side whose length is the base and the opposite side.

Bases of a trapezoid is the lengths of the parallel sides sides of the trapezoid.

Height of a trapezoid
is the perpendicular distance between the bases of the trapezoid.

## Vocabulary

Area is the number of square units covered by a figure.

Circle is the set of all points in a plane that are the same distance, called the radius, from a fixed point, called the center.

Radius is the distance between the center and any point on the circle.

Diameter is the distance across the circle through the center.

Circumference is the distance around the circle.

Pi is the ratio of the circumference of a circle to its diameter.

## Area of a Circle

A= PI*r^2

pi= 3.14, pi button on calculator, or 22/7

## Formula for Circumference

2*pi*r

pi= 3.14, pi button on calculator, or 22/7

Solid is a three-dimensional figure that encloses a part of space

Polyhedron is A solid that is enclosed with polygons

Face is a polygon that is a side of the polyhedron

Prism is a solid, formed by polygons, that has two congruent bases lying in parallel planes

Pyramid is A solid, formed by polygons, that has one base. The base can be any polygon, and the other faces are triangles

Cylinder is A solid with two congruent circular bases that lie in parallel planes

Cone is A solid with one circular base

Sphere is A solid formed by all points in space that are the same distance from a fixed point called the center

Edge is A line segment where two faces of the polyhedron meet

Vertex is A point at which three or more edges of a polyhedron meet
