Math Terms
Chapter 7 Geometry
| Term | Definition |
|---|---|
| Adjacent Angles | Two angles that share a common side and have the same vertex. |
| Congruent Angles | Angles that have the same measure. |
| Vertical Angles | Opposite angles formed by the intersection of two lines. Vertical angles are congruent. |
| Complementary Angles | Two or more angles with a sum of 90 degrees. |
| Supplementary Angles | Two or more angles with a sum of 180 degrees. |
| Perpendicular Lines | Lines that intersect to form right angles. |
| Parallel Lines | Lines in the same plane that do not intersect. |
| Transversal | A line that intersect two or more lines. |
| Scalene Triangle | A triangle with no congruent lines. |
| Isosceles Triangle | A triangle with exactly two congruent sides. |
| Equilateral Triangle | A triangle in which all sides are congruent. |
| Acute Triangle | A triangle in which all angles are acute. |
| Obtuse Triangle | A triangle that has exactly one obtuse angle. |
| Right Triangle | A triangle that has exactly one right angle. |
| Parallelogram | A quadrilateral with two pairs of congruent parallel sides. Opposite angels are congruent. |
| Rectangle | A parallelogram with four right angels. |
| Rhombus | A parallelogram with four congruent sides. |
| Square | A parallelogram with four congruent sides and four congruent angels. |
| Kite | A quadrilateral with two pairs of congruent, adjacent sides. Opposite sides are not congruent. |
| Trapezoid | A quadrilateral with exactly one pair of parallel sides. |
| Scale Drawing | A proportional, two-dimensional object that accurately represents an actual object. |
| Scale Model | A proportional, three-dimensional object that accurately represents an actual object. |
| Scale | A ratio that compares the measurements of the drawing or model to the actual measurements of an object. |
| Scale Factor | A scale without units (A scale can be written without units when the units are the same.) |
| Acute Angle | An angle with a measurement less than 90 degrees. |
| Right Angle | An angle with a measurement of exactly 90 degrees. |
| Obtuse Angle | An angle with measurement greater than 90 degrees, but less than 180 degrees. |
| Straight Angle | An angle with a measure of exactly 180 degrees. |
| Point | An exact location. It is the building block of geometry. |
| Line | A series of points with no end. |
| Plane | A perfectly flat surface that extends infinitely in all directions. |
| Ray | Part of a line with only one endpoint that extends without end in one direction. |
| Line Segment | Part of a line or ray that extends from on endpoint to another. |
| Angle | Two rays with a common endpoint. |
| Vertex | The common endpoint of two rays that form an angle. |
