you multiply 180 by the number of sides
A quadrilateral is a shape with four sides... It doesn't have *one* angle. The sum of the interior angles of a quadrilateral will always be 360 degrees, however, it is impossible to know the value an individual angle of a quadrilateral with the information given.
they arent quadrilateral has all sides equal and scalene has no sides equal (in measurement)
360 degrees
Quadrilaterals have a constant total angle measurement of 360 degrees
a quadrilateral has 4 (quad) sides. a square is a quadrilateral.
If it is a 4 sided quadrilateral then the 4th measurement is 96 degrees
For any quadrilateral (i.e. 4-sided figure), the angles will add up to 360 degrees. Since an obtuse angle is any angle with a measurement over 90 degrees, it is possible to have a quadrilateral with 3 obtuse angles. The fourth angle, however, must be acute (i.e. smaller than 90 degrees). Having 3 obtuse angles is not a requirement, however, for a quadrilateral.
when a quadrilateral is crossed over, so which means one line is crossed over another line then joins to make the shape.
All squares are quadrilaterals. All quadrilaterals are not squares. There is no square that is not a quadrilateral.
To find the measurement of the fourth angle in a quadrilateral when three angles are given, you can use the property that the sum of all angles in a quadrilateral is always 360 degrees. Given that the three angles are 90, 145, and 78 degrees, you can add these together and subtract the sum from 360 to find the measurement of the fourth angle. Therefore, the fourth angle would be 360 - (90 + 145 + 78) = 47 degrees.
A square is a quadrilateral, but not all quadrilaterals are squares. A quadrilateral is just a four-sided figure.
90 degrees each for a total of 360 degrees.
