Angles&Quadrilateral
Angle & Quadrilateral Definitions
| Question | Answer |
|---|---|
| Quadrilateral | Any 4-sided shape. |
| Trapezoid | A 4-sided shape with exactly 1 pair of parallel sides. |
| Parallelogram | A 4-sided shape with 2 pairs of parallel sides. |
| Rhombus | A 4-sided shape with 4 congruent sides. |
| Rectangle | A 4-sided shape with 4 congruent angles. |
| Square | A 4-sided shape with 4 congruent sides AND 4 congruent angles. |
| Vertical Angles | Angles formed by intersecting lines. They are across from each other and are congruent. |
| Adjacent Angles | Angles that share a vertex and one side. |
| Supplementary Angles | Angles that add up to 180 degrees or form a straight line. |
| Complementary Angles | Angles that add up to 90 degrees or form a right angle. |
| Corresponding Angles | The angles in matching corners are called |
| Alternate Interior Angles | Each pair of these angles are inside the parallel lines, and on opposite sides of the transversal. |
| Alternate Exterior Angles | Each pair of these angles are outside the parallel lines, and on opposite sides of the transversal. |
| Transversal | When two lines are crossed by a third line. |
| Angles in a Triangle | The sum of the interior angles is 180 degrees. |
| Angles in a Quadrilateral | The sum of the interior angles is 360 degrees. |
