| Line Of Symmetry | The line that divides something in half so that one half is the mirror image of the other half. There may be more than one. |
| Scale Drawing | A drawing or plan on which the real object is made bigger or smaller while keeping the same proportions. |
| Scale Model | A representation or copy of an object that is larger or smaller than the actual size of the object being represented. |

| Dilation | A representation or copy of an object that is larger or smaller than the actual size of the object being represented. |
| Perspectives | When drawing on paper, we can show depth by drawing all parallel lines running into one or several points on the horizon. These points are called vanishing points. The drawing looks like it is 3-dimensional. |
| Perpendicular | Forming a right angle. |
| Isoceles Triangle | Two sides have the same length and two angles have the same measure. |
| Scalene Triangle | Each side is different in length. |
| Equilateral Triangle | Three sides of equal length and three equal angles. |
| Right Triangles | Has a right angle. |
| Legs | Either of the two sides that form the right angle of a right triangle. |
| Hypotenuse | The side opposite the right angle in a right triangle. |
| Congruent | Exactly equal. Matching exactly. Two figures that have the same shape and the same size. |
| Adjacent | Positioned next to each other, having a common point or side. |
| Circumference | The distance around a circle. |
| Perimeter | The distance around a closed shape, or the length of its boundary. |
| Area | The amount of surface or the size of a surface. It is measured in square units. |
| Lateral Surface Area | The face or surface of a solid on its sides. That is, any face or surface that is not a base. |
| Total Surface Area | The total area of the exterior surface of a solid. |
| Volume | The amount of space inside a container, or the actual amount of material in the container. |
| Face | In a 3-dimensional shape, the flat part of the surface that is bounded by the edges. |
| Edge | In geometry, the line that is the intersection of two plane faces. |
| Pyramids | A solid (3D shape) which has a polygon for a base and traingles for all the other faces. |
| Cones | A solid which has a circular base and comes in to a point at the top. |
| Spheres | A 3-dimensional shape like a round ball. It has one curved surface and no corners or edges. Every point on the surface is the same distance from the center. |
| Prisms | A solid figure with two faces that are parallel and the same in size and shape. They can be any polygon. |
| Line | A straight path of points that extends forever in both directions. It is the shortest distance between two points. |
| Line Segment | Part of a straight line. |
| Plane | A flat surface, like the floor of a house or a wall. It extends infinitely in all directions. |
| Quadrilaterals | A plane shape with four sides and four angles. |
| Complementary Angle | Two angles for which the sum of their measure is 90 degrees. |
| Vertex | Top, the highest part or point. A point where two or more adjacent lines meet to form an angle or a corner. In plane or solid figures, the point opposite the base. |
| Supplementary Angle | Two angles for which the sum of their measures is 180 degrees. |
| Diameter | A line segment joining two points of a circle and passing through the center of the circle. It equals two radii (r). |
| Center Of A Circle | A point that is the same distance from all points on the circumference. The distance is called the radius (r). |
| Obtuse Angles | This is bigger than a right angle (90 degrees) but smaller than a straight angle (180 degrees). |
| Acute Angles | A sharply pointed angle with size less than a right angle (90 degrees). |
| Pythagorean Theorem | In any right triangle, the square of the hypotenuse is equal to the sum of the squares of the sides. |
| Pythagorean Triples | Three integers a, b, and c that satisfy a² + b² = c². |
| Net | A flat pattern that can be cut out, folded and glued together to make a 3-dimensional model of a solid. |
| Diagonal | A line segment joining two corners that are not next to each other in any polygon. |
| Altitude | Height. How high something is above the surface of the earth, sea level, or horizon. It is the length of perpendicular height from base to vertex. |
| 2-Dimensional | When something has length and width. |
| 3-Dimensional | When something has length, width, and height. |
| Nth term | A formula with ‘n’ in it which enables you to find any term of a sequence without having to go up from one term to the next. |
| Algebraic Expression | One or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs. It's only a phrase, not the whole sentence, so it doesn't include an equal sign. |
