Quadrilaterals Project 1-4-13 Geometry D Block

The Square A square has 4 congruent sides and all 4 angles are a right angle ( 90o) Diagonals congruent. Diagonals bisect each other. Diagonals perpendicular.

Rectangle All the angles are right angles. Opposite sides are congruent and parallel. Diagonals are congruent. Diagonals bisect each other

Rhombus 2 pair of congruent sides, opposite sides are parallel. Adjacent sides congruent. Opposite angles congruent. Diagonals bisect each other. Diagonals perpendicular.

Parallelogram Opposite sides parallel and congruent. Opposite angles congruent. Adjacent angles supplementary. Diagonals bisect each other.

Trapezoid Only 1 pair of opposites sides are parallel .

Isosceles trapezoid One pair of parallel sides and those parallel sides are not congruent and other pair of sides congruent, not parallel. Diagonals congruent.

Conclusion In a quadrilaterals the sum of all angles are equal 360. some quadrilaterals each angle equal 90. some are not equal 90 but it’s still equal 360.
