Quadrilateral is a polygon with 4 sides. Some quadrilaterals have properties that classify them as special quadrilaterals. Here are six major special quadrilaterals. A parallelogram has both pairs of opposite sides parallel and congruent. Both pairs of opposite angles are congruent.
A rectangle has four right angles. A rhombus has four congruent sides.
A square has four congruent sides and four right angles. Atrapezoidhas exactly one pair of parallel sides.
Quadrilateral Opposites sides are parallel Parallelogram Rhombus Rectangle 4 right angles Square 4 equal sides long sides are equal short sides are equal Trapezoid Only 1 set of parallel sides 4 sided shape
2 3 1 4 You can put two triangle together to form a Quadrilateral 180 180 The sum of the measures of the angles in a quadrilateral is 360°. m1 + m2 + m3 + m4 = 360°
89° 82° 65° x Find the unknown angle measure in the quadrilateral. 65° + 89° + 82° + x = 360° EX1) 236° + x = 360° –236° –236° x = 124° 67° + 92° + 89° + x = 360° 92° EX2) 248° + x = 360° 89° 67° –248° –248° x x = 112°
