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 three acute angles and one right angle?
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.
What does a trapezoid with three right angles look like?
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
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.
Is quadrilateral with at least three right angles is a rectangle?
if a quadrilateral has three right angles will also have have a fourth right angle. Making it a rectangle. The addition of all the angles in a triangle is 360 degrees. If there are three right angles, and you subtract their addition by 360, you will get ninty degrees.
What are three names for a polygon that has four equal sides and no right angles?
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
How many right angles do a right triangle have?
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
Is a quadrilateral with one right angle necessarily a rectangle?
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
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.
Is an isosceles triangle a quadrilateral?
No. Triangles have three angles and three sides. A quadrilateral has four angles and four sides.
Maximum obtuse angles in quadrilateral?
There can be at most 3 obtuse angles in a quadrilateral.
Which quadrilateral always have a 90-degree angles?
The only quadrilaterals that always have all four right angles are the square and the rectangle. All four angles in a quadrilateral must add up to 360 degrees.It is possible to have non-regular quadrilaterals with one or two right angles. A quadrilateral with three right angles becomes either a square or a rectangle, because its fourth angle must also be a right angle.
