6. 1 Classifying Quadrilaterals

Special Quadrilaterals A parallelogram is a quadrilateral with both pairs of opposite sides parallel. A rhombus is a parallelogram with four congruent sides. A rectangle is a parallelogram with four right angles. A square is a parallelogram with four congruent sides and right angles. A kite is a quadrilateral with two pairs of adjacent sides congruent and no opposite sides congruent. A trapezoid is a quadrilateral with exactly one pair of parallel sides. The isosceles trapezoid at the right is a trapezoid whose nonparallel sides are congruent.

Classifying Quadrilaterals

Classifying Quadrilaterals Examples: Judging by appearance, classify the quadrilaterals in as many ways as possible. Most Specific Name:

Classifying Quadrilaterals Use slope and distance to determine the most precise name for quadrilateral LMNP with vertices L(1, 2), M(3, 3), N(5, 2), and P(3, 1). Slopes: Distances:

Classifying Quadrilaterals Use slope and distance to determine the most precise name for quadrilateral EFGH with vertices E(-3, 1), F(-7, -3), G(6, -3), and H(2, 1). Slopes: Distances:

Using Properties Find the values of the variables for the kite. Find the values of the variables for the rhombus. Then find the lengths of the sides.
