What is a quadrilateral with 3 acute angles and 1 obtuse angle?

A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.


Can a quadrilateral have 3 obtuse angles and 1 right angle?

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.

How do you draw a quadrilateral with 1 reflex 1 obtuse and 2 acute angles?

Well, honey, to draw a quadrilateral with 1 reflex, 1 obtuse, and 2 acute angles, you'll need to start by sketching a shape with 1 angle greater than 180 degrees (that's your reflex angle), 1 angle greater than 90 degrees (that's your obtuse angle), and 2 angles less than 90 degrees (those are your acute angles). Just make sure all the angles add up to 360 degrees, and you'll have yourself a sassy quadrilateral!

Can a quadrilateral be made with 3 acute angles and 1 right angle?

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.


How many obtuse angle does a irregular polygon have?

This depends on the polygon.For a triangle (3-sides) : maximum 1 obtuse angle.Quadrialteral (4-sides): maximum 3 obtuse angles.For polygons with more sides, it is possible for all angles to be obtuse.


How many different types of pentagons are there?

It depends on how they are classified. They can have 1 to 4 acute angles, they can have 1 to 4 right angles, they can have 1 to 5 obtuse angles. The individual values of the angles will generate different pentagons. They can be regular or irregular. They can be convex or concave.
