The sum of the interior angles of a quadrilateral is 360 degrees so if 3 of them are right angles (90 °) the remaining fourth angle must also be 90 °.
360° - 3x90° = 90°

How many right angles can a quadrilateral have?
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
What is the surface area of a quadrilateral?
Well it matters if you put it in a 3-dimensional or a 2-dimensional figure because if you turn it into a 3-dimensional figure the the surface would have a flat surface with volume and area.If you draw a quad in 2-D then the figure you draw is the surface.
Can you draw a triangle with 2 right angles?
Yes you can. The problem is on what surface you draw the triangle. On a plane this would be impossible, but if you do it on a spherical surface then you can even draw a triangle with 3 right angles.
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.
Can you draw a square with 3 lines?
you draw a square with 3 lines inside it.
Why can't you draw trapezoid with 3 right angles?
if a figure is a square, then it is a regular quadrilateral
Can you draw a quadrilateral with exactly 3 lines of symmetry?
no.
Does a quadrilateral have three congruent angles?
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.
Why is it impossible to draw a quadrilateral with 3 acute triangles?
It's entirely possible to draw a quadrilateral with 3 acute angles.The fourth angle must be obtuse or reflex, but so what ? !
Can you draw a quadrilateral that has three right angles?
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
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.
Is a right triangle not a quadrilateral?
A right triangle is not a quadrilateral. In fact, no triangle is a quadrilateral. The definition of a quadrilateral is having 4 sides, while all trianlges must have 3 sides, making a triangle that is a quadrilateral impossible.
3 of the angels of a quadrilateral mesure 80 100 and 55 which mesure is the fourth angle?
125 degrees
How many obtuse angles can a quadrilateral have?
3 you cant draw one with four
What shape has 2 sets of parallel sides has 4 right angels all sides are the same length what are the 3 names?
This shape is a square. A square is a type of rectangle, which is a type of parallelogram, which is a type of quadrilateral.
Which is not a quadrilateral a rhobus a rectangle a right triangle or a trapezoid?
A right triangle is not a quadrilateral. A quadrilateral is a polygon with four sides, while a right triangle has only three sides.
What polygon does not have right angles but is a quadrangle?
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
