It isn't possible to predict what any of the angles is individually, and different quadrilaterals can have all kinds of different angles inside them. But the one thing that we do know: All four of the angles inside any quadrilateral must add up to 360 degrees.
The only quadrilaterals that always have all four right angles are the square and the rectangle. All four angles in a quadrilateral must add up to 360 degrees.It is possible to have non-regular quadrilaterals with one or two right angles. A quadrilateral with three right angles becomes either a square or a rectangle, because its fourth angle must also be a right angle.
congruent
Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.
They must be the same.
