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)
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
yes
If one of the angles is 90 degrees then it is right ange triangle If one of the angles is obtuse then it is an obtuse triangle If the three angles are 3 different acute then it is a scalene triangle If two of the angles are equal then it is an isosceles triangle If the three angles are equal then it is an equilateral triangle
A scalene triangle can have an obtuse angle and two different acute angles or three different acute angles but all angles in a triangle must add up to 180 degrees.
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.

There can be at most 3 obtuse angles in a quadrilateral.
You know that at least one of them must be acute. A quadrilteral can have three obtuse angles, but not four.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
No not never can a triangle have 3 obtuse angles but it can have 3 acute angles
yes
Yes you can, as long as the four angles (obviously three of which will be less than 90 degrees) end up with a sum of 360 degrees, meaning there will have to be at least one obtuse angle in a non-square quadrilateral.
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
The angles are, acute, obtuse, right, straight, and reflex.
