- Are closed figures consisting of four line segments or sides. These sides may or may not be congruent and parallel.

Which One Does Not Have These Properties? Opposite sides are congruent. Opposite sides are parallel. Opposites angles are congruent. Because: opposite sides are NOT congruent opposite sides are NOT parallel opposite angles are NOT congruent Trapezoid

Which One Does Not Have These Properties? Has 4 sides. Only two sides are parallel Because: Parallelogram a parallelogram has four sides but more than two sides are parallel--a parallelogram has opposite sides that are parallel.

Which One Does Not Have These Properties? Has 4 sides. All sides are congruent. Opposite sides are parallel. All angles are right angles Because: a rectangle has four sides opposite sides are parallel all angles are right angles but all sides are NOT congruent Rectangle

Which One Does Not Have These Properties? Has 4 sides. Has two pairs of congruent adjacent sides. Trapezoid Because: a trapezoid has four sides two pair of adjacent sides the two pairs of adjacent sides are NOT congruent

Which One Does Not Have These Properties? Has 4 sides. Opposite sides are congruent. Opposite sides are parallel. All angles are right angles. Because: Parallelogram a parallelogram has four sides opposite sides are congruent opposite sides are parallel but all angles are NOT right angles

Which One Does Not Have These Properties? Has 4 sides. All sides are congruent. Opposite sides are parallel. No angles=90°. Parallelogram Because: a parallelogram has four sides opposite sides are parallel no angles = 90° but all sides are NOT congruent on figure c.

1. Which figure satisfies these properties? Has 4 sides Opposite sides are congruent. Opposite sides are parallel. Opposite angles are congruent. Parallelogram

2. Which figure satisfies these properties? Has 4 sides. Only two sides are parallel. Trapezoid

3. Which figure satisfies these properties? Has 4 sides All sides are congruent. Opposite sides are parallel. All angles are right angles. Square

4.Which figure satisfies these properties? Has 4 sides Has two pairs of congruent adjacent sides. Kite

5. Which figure satisfies these properties? Has 4 sides Opposite sides are congruent. Opposite sides are parallel. All angles are right angles. Square

6. Which figure satisfies these properties? Has 4 sides All sides are congruent. Opposite sides are parallel. Opposite angles are congruent. No angles=90° Parallelogram
