## VOCABULARY

*:*

**2-Dimensional**A shape that only has two dimensions (such as width and height) and no thickness.

*:*

**3-Dimensional**An object that has height, width and depth (thickness), like any object in the real world.

*:*

**Area**The number of square units it takes to completely fill a space or surface.

*:*

**Bases of a Prism**The two faces formed by congruent polygons that lie in parallel planes, all of the other faces being parallelograms.

*:*

**Cubic Units**Volume of the solids is measured in Cubic Units.

*:*

**Edge**The intersection of a pair of faces in a three-dimensional figure.

*:*

**Equilateral Triangle**A triangle which has all three of its sides equal in length.

*:*

**Face**One of the polygons that makes up a polyhedron.

*:*

**Fractional edge length**The length of each edge of the cube is a fraction.

*:*

**Isosceles Triangle**A triangle which has two of its sides equal in length.

*:*

**Kite**A quadrilateral with two distinct pairs of equal adjacent sides. A kite-shaped figure.

*:*

**Lateral Faces**In a prism, a face that is not a base of the figure.

*:*

**Net**A two-dimensional figure that, when folded, forms the surfaces of a three-dimensional object.

*:*

**Parallelogram**A quadrilateral with both pairs of opposite sides parallel.

*:*

**Polygon**A number of coplanar line segments, each connected end to end to form a closed shape. A regular polygon has all sides equal and all interior angles equal. An irregular polygon sides are not all the same length nor does the interior angles have the same measure.

*:*

**Polyhedron**A 3-dimensional figure that has polygons as faces.

*:*

**Prism**A polyhedron with two parallel and congruent faces, called bases, and all other faces that are parallelograms.

*:*

**Quadrilaterals**Four coplanar line segments linked end to end to create a closed figure. A 4-sided polygon.

*:*

**Rectangle**A 4-sided polygon where all interior angles are 90°.

*:*

**Rectangular prism**A solid (3-dimensional) object which has six faces that are rectangles.

*:*

**Rhombus**A quadrilateral with all four sides equal in length.

*:*

**Right Triangle**A triangle where one of its interior angles is a right angle (90 degrees).

*:*

**Right rectangular prism**In a right prism, the lateral faces are each perpendicular to the bases.

*:*

**Scalene Triangle**A triangle where all three sides are different in length.

*:*

**Square**A quadrilateral that has four right angles and four equal sides.

*:*

**Surface area**The total area of the 2-dimensional surfaces that make up a 3-dimensional object.

*:*

**Trapezoid**A quadrilateral which has one pair of parallel sides.

*:*

**Triangles**A closed figure consisting of three line segments linked end-to-end. A 3-sided polygon

*:*

**Triangular prism**A prism whose bases are triangles. A solid (3-dimensional object what has five faces: three rectangles and two bases.

*:*

**Vertices**The common endpoint of two or more rays or line segments

*:*

**Volume**The amount of space occupied by an object.

*:*

**Volume of a Prism**The area of a base times the height. The number of cubic units to fill a prism.
