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
FINDING THE 4TH ANGLE INQUADRILETERALS
LETS MOVE ON Click Here
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°

Now that were all done lets go over what we studied
What is a quadrilateral –a polygon with 4sides and 4 angles
what do the angles = in a quadrilateral- 360°
How do you find the missing angle in a quadrilateral by adding the numbers together then subtracting them buy 360
