A quadrilateral has 360o and it has 4 sides so...
360o - (98o + 125o + 90o) = 47o
So the missing degree is 47o
you see if it equals to 360 degrees or 180 degrees then you add the sides that they have gave you and see if it is correct.
4 sides requires Total interior angles of 360 degrees 360-90-90-91= 89
Square Or a rectangle, which also has 4 sides and 4 90 degree angles.
Angles are measured in degrees, not sides.
360 degrees
A quadrilateral has a total of 360 degrees. This is because a quadrilateral is a polygon with four sides, and the sum of the interior angles of any quadrilateral always adds up to 360 degrees. This property can be proven using the formula (n-2) x 180 degrees, where n is the number of sides of the polygon.
A square. Four 90 degree angles allow a quadrilateral to have equal sides.
Not necessarily. The literal meaning of quadrilateral is 'four sides' - this can mean any four-sided shape. A rhombus and a trapezoid are both quadrilaterals - but neither has angles of 90 degrees.
When you add all four sides of a quadrilateral(all parallelograms are quadrilateral), It must equal 360 degrees. So what you do is you add up the three angles that are given, them subtract that sum from 360.
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero degrees.
A quadrilateral has 4 sides and 4 interior angles that add up to 360 degrees.
