How to find an angle in a quadrilateral?
- The angles inside a quadrilateral add to 360°.
- To find the missing angle, add up the 3 known angles and subtract this from 360°.
- 75° + 85° + 140° = 300°. The three known angles add to 300°.
- We subtract this from 360°. 360° – 300° = 60° and so the missing angle is 60°.

What is a quadrilateral with four sides?
If you connect the four linear objects at their eight ends, you have a quadrilateral, a four-sided polygon. Maybe you arranged four sides so the shape looks full, which means you made a convex quadrilateral. Maybe your four line segments made a pointy shape like an arrowhead; you made a concave quadrilateral.

Quadrilaterals appear in four different classifications: Convex -- Each interior angle is less than 180° and the two diagonals are inside the closed space of the quadrilateral. Concave -- One interior angle is greater than 180° and one diagonal lies outside the shape. Simple -- The quadrilateral does not cross its sides (it is not self-intersecting)

Why are the top and bottom sides of a quadrilateral parallel?
Thus, the top and bottom sides of the quadrilateral are parallel because the angles marked by a single arc are congruent, and the left and right sides of the quadrilateral are parallel because the angles marked by double arcs are likewise congruent . These are but two possible approaches to solving this problem.
