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.
Yes The definition of a rectangle is a quadrilateral with four right angles. So the angles are the same
No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.
Yes. The reason why is because a rectangle is a quadrilateral with four right angles and a rhombus can have four right angles and it is also a quadrilateral.
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
A rectangle has no acute angles and no obtuse angles. It has 4 right angles.
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.
A rectangle is a quadrilateral with four right angles True (Apex)
A quadrilateral with 4 right angles is a rectangle
is a rectangle
Right angles.
A quadrilateral having four right angles is called a rectangle.
A rectangle or square.
This is a rectangle.
A rectangle is a quadrilateral with all right angles. A square has 4 right angles AND 4 sides (which means it's a quadrilateral), so it's a rectangle.
a rectangle is any quadrilateral with four right angles
No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
A square or rectangle.
