The interior angles of a quadrilateral must always add up to 360 degrees.
The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
360 degrees
The four angles of a quadrilateral add up to 360 degrees.
360 degrees
The 4 interior angles of a quadrilateral add up to 360 degrees
Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°
50 degrees (360 degrees in a quadrilateral)
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.
90 degrees each for a total of 360 degrees.
4
It is: 47 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 sum is two straight angles or 360 degrees.
