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

a quadrilateral is a polygon-(closed sided figure w/straight lines) w/ four sides and four angles they 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

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°
