Question | Answer |
---|---|
Area | The number of square units needed to cover the inside of a region or plane figure. |
Cone | A 3-dimensional figure with a curved surface, a circular base, and one vertex. |
Cube | A 3-dimensional figure with six congruent square faces, * vertices and 12 edges |
Cubic Unit | A unit for measuring volume, such as a cubic inch or a cubic centimeter. |
Cylinder | A 3-dimensional figure having two parallel congruent circular bases and a curved surface connecting the two bases. |
Perimeter | The distance around a shape or region |
Rectangle | A quadrilateral with four right angles; opposite sides are equal and parallel |
parallelogram | A quadrilateral with four sides in which each pair of opposite sides are parallel and equal in length. |

Plane Figure | A 2-dimensional figure that lies entirely within one plane such as a triangle or square. |
Polygon | A closed plane figure formed using line segments that meet only at their endpoints. |
pyramid | A solid figure with a polygon as a base and triangular shaped faces that share a common vertex. |
prism | A 3-dimensional figure with two parallel, congruent polygons as bases and parallelograms for faces. |
perpendicular lines | Lines that meet or cross each other to form right angles. |
Acute Angle | An angle with a measure greater than 0° and less than 90°. |
congruent angles | Angles with the same measure. |
Edge | The line segment where two faces of a 3-dimensional figure meet. |
Endpoint | The point at either end of a line segment or the point at the beginning of a ray. |

rhombus | A parallelogram with four congruent sides. |
Right Angle | An angle with a measure of 90°, formed by perpendicular lines. |
Translation/Slide | To move a figure along a line in any direction for a given distance. Also called a translation. |
Sphere | A 3-dimensional figure that is set of all points that are the same distance from a given point, called the center. |
Square | A rectangle with four congruent sides. |
Square Unit | A unit for measuring area, such as square inch or square centimeter. |
Straight Angle | An angle with a measure of 180°. |
line symmetry | A line that can be drawn through the figure which splits the figures into 2 halves that match. |
Trapezoid | A quadrilateral with exactly one pair of parallel sides. |
triangular prism | A prism whose bases are triangular with parallelograms for sides. |
triangular pyramid | A pyramid whose base is a triangle. |
Rotaion | The process of moving or turning a figure around a point. |
Vertex | The point where two rays meet in an angle. |
Volume | The number of cubic units needed to fill a 3-dimensional figure or solid figure. |
Width | The measurement of distance from side to side telling how wide. |
three-dimensional figure (3-D) | A figure that has length, width, and height. |
