Quadrilaterals Kimberly A. Yuretich
Objectives To identify any quadrilateral, by name, as specifically as you can, based on its characteristics
Quadrilateral a quadrilateral is a polygon with 4 sides.
Specific Quadrilaterals There are several specific types of quadrilaterals. They are classified based on their sides or angles.
A quadrilateral simply has 4 sides – no other special requirements.
Examples of Quadrilaterals
A parallelogram has two pairs of parallel sides.
Parallelogram Two pairs of parallel sides opposite sides are actually congruent.
A rhombus is a parallelogram that has four congruent sides.
Rhombus Still has two pairs of parallel sides; with opposite sides congruent. 4 in.
A rectangle has four right angles.
Rectangle Still has two pairs of parallel sides; with opposite sides congruent. Has four right angles
A square is a specific case of both a rhombus AND a rectangle, having four right angles and 4 congruent sides.
Square Still has two pairs of parallel sides. Has four congruent sides Has four right angles
A trapezoid has only one pair of parallel sides.
An isosceles trapezoid is a trapeziod with the non-parallel sides congruent.
Trapezoid has one pair of parallel sides. Isosceles trapezoid trapezoids (Each of these examples shown has top and bottom sides parallel.)
An kite is a quadrilateral with NO parallel sides but 2 pairs of adjacent congruent sides.
Example of a Kite 2 in. 4 in. 2 in.

Warm Up The lengths of three sides of a triangle are given. Classify the triangle , 12, , 10, , 15, 26 equilateral scalene isosceles.
WARM UP: What is the definition of Congruent?
PinpointingProperties. Trapezoids Make these trapezoids on your geoboard. How many sides? How many angles? Are any sides congruent? No sides are congruent.
1.6 Classifying Quadrilaterals
Proving That Figures Are Special Quadrilaterals
Polygons with 4 sides and 4 angles
8.6 – Identify Special Quadrilaterals
A Four Sided Polygon! 1.BOTH pairs of opposite sides are parallel 2.BOTH pairs of opposite sides are congruent.
Activity In your group, you will be given a card. You will be using a Bubble Map to describe the shape. In the middle of the Bubble Map, please draw the.
