Impossible. You cannot have an obtuse angle without an acute angle in a quadrilateral.
It is just an irregular quadrilateral.
isolese triangle
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
They will be acute angles.
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
A trapezoid can have 2 right angles, an obtuse and an acute angle Or a kite.
it is an irregular shape
an obtuse angle has 2 angles. Obtuse angle: _/-acute / right
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
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.
it has No acute or obtuse angles
