a quadrilateral is a polygon-(closed sided figure w/straight lines) w/ four sides and four angles. there are many types but these are the 5 most common like:

Ex.

What is a Quadrilateral

Rectangle-4 right angles

Parallelogram- 4

parallel angles

Square-4 right

angles 4 congruent

sides

Trapezoid-one pair of

parallel lines

Rhombus-all sides

congruent

Quiz 1

Polygons w/ 4 sides and angles

Polygons w/any sides any angles

The sum of the interior angles of a quadrilateral are equal to 360o. To find the fourth angle of a quadrilateral when the other three angles are known, subtract the number of degrees in the other three angles from 360o.

Example: How many degrees are in the fourth angle of a quadrilateral whose other three angles are 80o and 110o and 95o? Answer: 360o - 80o - 110o - 95o = 75o

1. What are the sum of the interior angles =

2. What is an x angle of the quadrilateral

the missing angle a variable used to measures of the shape substitute for #

Quiz 2

360 260 or

Angles of a QuadrilateralAngles in a quadrilateral would always

= 360° no matter what so the goal is to find

the missing angle out of 360

Ex.What is the missing angles

measurements?

Use 360-90-90-75=105°

That is the missing angles measurements so x=105°

90° 90°

75° x°
