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

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

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

Use 360-90-90-75=105°
That is the missing angles measurements so x=105°
