QUADRILATERALS SPI: 6.4.1 Identify, define or describe geometric shapes given a visual representation or written description of its properties.
QUADRILATERAL • A quadrilateral is a closed figure with four sides and four angles. • They are named based on their sides and angles.
The sum of the angles of all quadrilaterals is 360°. • Angle 1 + angle 2+ angle 3 + angle 4 = 360° 360°
Rectangle • A rectangle is a quadrilateral with opposite sides parallel and all angles are right
Parallelogram • A quadrilateral with opposite sides parallel and opposite sides congruent
SQUARE • A quadrilateral with all sides congruent, all angles are right and opposite sides are parallel
RHOMBUS • A quadrilateral with all sides congruent, opposite sides parallel and opposite angles congruent
TRAPEZOID • A quadrilateral with one pair of opposite sides parallel Parallel lines
