quadrilateral means having all sides the same length. when you make a shape with 3 obtuse angles and with the same length on the sides, only 3 of them will have the same length which is the sides of the 3 obtuse angles. then the last side will be too long. obviously it is no more quadrilateral.
isolese triangle
A certain type of a quadrilateral can have 3 obtuse angles providing that all of its 4 interior angles add up to 360 degrees
it is an irregular shape
No not never can a triangle have 3 obtuse angles but it can have 3 acute angles
There can be at most 3 obtuse angles in a quadrilateral.
No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.

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.
A quadrilateral kite can have two obtuse angles and two acute angles that add up to 360 degrees.

3 you cant draw one with four

An obtuse triangle can have at most one obtuse angle.A quadrilateral can have up to 3.Every regular polygon (shapes with equal sides and angles) with more sides than a square has obtuse angles.PentagonHexagonHeptagonOctagonNonagonDecagon
A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
Quadrangle isn't a polygon. Quadrilaterals are polygons. One's with possibilities of no right angles include: Kite Parallelogram Rhombus Complex Quadrilateral Simple Quadrilateral Concave Quadrilateral Convex Quadrilateral Tangential Quadrilateral Cyclic Quadrilateral Bicentric Quadrilateral Trapezium Isosceles Trapezium 3-Sided-Equal Trapezium
