Hexagon | A polygon with six sides. |
Isosceles Triangle | A triangle with at least two congruent sides and two congruent angles. |
Kite | A convex quadrilateral with two distinct pairs of adjacent, congruent sides. |
Line | A set of points that form a straight path extending infinitely in two directions. |
Line of Symmetry | A line dividing a two-dimensional figure into two parts that are mirror images of each other. |
Line Segment | A part of a line. A line segment has two endpoints and a definite length. |
Nonagon | A polygon with nine sides. |
Obtuse Angle | An angle that is greater than 90 degrees but less than 180 degrees |
Obtuse Triangle | A triangle that has one obtuse angle. |
Octagon | A polygon with eight sides. |
Parallel Lines | Lines lying in the same plane that are always the same distance apart. |
Parallelogram | A quadrilateral with both pairs of opposite sides parallel. Opposite angles are congruent. |
Pentagon | A polygon with five sides. |
Perimeter | The distance around a figure. |
Perpendicular | At right angles. |
Plane | A flat surface extending infinitely in all directions. |
Point | The smallest geometric unit. A position in space, often represented by a dot. |
Polygon | A simple, closed, plane figure bounded by straight sides. |
Quadrilateral | A polygon with four sides. |
Ray | A set of points that form a straight path extending infinitely in one direction. A ray has one endpoint. |
Rectangle | A parallelogram with four right angles. Opposite sides are congruent and parallel. |
Reflection | A transformation of a geometric figure that results in a mirror image of the original. |
Regular Polygon | A polygon that has equal sides and equal angles. |
Rhombus | A parallelogram with four congruent sides. Opposite angles are congruent. |
Right Angle | An angle that is one-fourth of a full turn. A right angle measures 90 degrees. |
Right Triangle | A triangle that has one right angle. |
Scalene Triangle | A triangle with no sides congruent. |
Similar Figures | that have the same shape but not necessarily the same size. |

Sphere | A three-dimensional figure formed by a set of points that are all the same distance from a fixed point called the center. |
Square | A rectangle with congruent sides. |
Symmetry | If a figure can be folded along a line so that the two halves match exactly, then the figure has line symmetry. |
Three-Dimensional | Relating to objects that have length, width, and depth. Solid figures such as polyhedra, cones, and spheres are three-dimensional. |
Translation | A transformation in which a geometric figure is formed by moving every point on a figure the same distance in the same direction. |
Trapezoid | A quadrilateral with exactly one pair of parallel sides. |
Triangle | A polygon with three sides. |
Triangular Prism | A prism in which the bases are triangles. |
Two-Dimensional | Relating to figures that have length and width but not depth. Figures such as polygons and circles are two-dimensional. |
Vertex | A point at which two line segments, lines, or rays meet to form an angle. |
