What you really need to know!
A quadrilateral is a closed figure with four sides and four vertices. Squares, rectangles, and trapezoids are examples of quadrilaterals.
What you really need to know!
The sum of the angles of a quadrilateral is 360°.
Example 1:
Find the value of x. Then find each missing angel measure.
Example 1:
4x + 110 + x + 75 = 3605x + 185 = 3605x = 175x = 35
