Reviewer first Quarterly Math 4 Quadrilaterals: A Parade of Four-Sided Polygons Quadrilaterals There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles. Side Angle All polygons are made up of line segments and angles. The line segments that create quadrilaterals will be parallel, perpendicular, OR intersecting. The adjacent sides of this quadrilateral are perpendicular. The adjacent sides of this quadrilateral are The opposite sides intersecting. of this quadrilateral are parallel.  Squares A square is a quadrilateral that has four equal sides and four right angles. This square has four right angles and all four sides are congruent (the same length). How many pairs or sets of parallel sides do you see?  Rectangles A rectangle is a quadrilateral that has two pairs of parallel sides that are equal and four right angles. This rectangle has four right angles and two pairs of parallel sides that are congruent. If all four sides were equal, would this shape still be a rectangle?  Rhombuses A rhombus is a quadrilateral that has four equal sides and two pairs of parallel sides. This rhombus has four congruent sides and two pairs of parallel sides. Can a square be a rhombus?  Trapezoids A trapezoid is a quadrilateral that has one pair of parallel sides. This trapezoid has one pair of parallel sides. Can you identify which two sides are parallel? Do trapezoids have to have sides that are congruent? parallelograms A parallelogram is a quadrilateral that has two pair of parallel sides. This parallelogram has two pairs of parallel sides. Can you draw a parallelogram that looks different than this one?  Perimeter The total distance around the edge of a shape Perimeter of a Parallelogram This is the common scenario, when we have the length of two adjacent sides of a parallelogram given to us. Thus, we can simply the formula: Perimeter of a parallelogram = 2 (l + w) Or l +l+w+w
