If you are suggesting they add up to less than 180, this is impossible.
If you are suggesting that each angle is less than 180, this is always the case.
A right angle triangle
The measure of each interior angle of a quadrilateral is always less than 360 degrees, as the sum of all interior angles in a quadrilateral is 360 degrees. This means that each individual angle must be less than 360 degrees, but it can vary widely depending on the specific type of quadrilateral. For example, in a rectangle, each angle is 90 degrees, while in an irregular quadrilateral, the angles can differ significantly.
A angle less than 90 degrees is a acute angle.
The figure described is a quadrilateral known as a right-angled trapezoid. It has three right angles (90 degrees) and one angle that is less than a right angle (acute) and one angle that is greater than a right angle (obtuse). This configuration allows the sum of the angles to equal 360 degrees, satisfying the angle sum property of a quadrilateral.
