Using trigonometry the area of the quadrilateral works out as 16.688 square cm rounded to three decimal places
is an exterior angle of a quadrilateral always sometime or never 90 degrees
A vertex of a quadrilateral can have any measure between (but excluding) 0 degrees and 360 degrees. The only requirement is that the four angles add to 360 degrees. So a quadrilateral can have angles of 0.1, 0.1, 0.1 and 359.7 degrees.
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
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.
360 degrees
360 degrees
Yes, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
360 degrees are supposed to be in a quadrilateral so 360 - 270 = 90 degrees
The sum of the interior angles of a quadrilateral is 360 degrees.
The angles of a quadrilateral add to 360 degrees.
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.
By sketching a diagram and then using trigonometry the area of the 4 sided quadrilateral works out as 0.305 square cm to three decimal places
