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. |
