They can only have four
A shape with no right angles but is still a quadrilateral is called a rhombus. A rhombus has four sides of equal length and opposite sides that are parallel to each other. Although its angles are not right angles, they are all congruent.
Rectangles have four sides and four angles.
A rhombus does not have four right angles. A square has four right angles, as does a rectangle.
Yes, a rectangle has four right angles.
A rectangle has four right angles but is not a square.
A square has FOUR right angles. Each corner is a right angle.
A four sided figure with four equal sides and no right angles is a diamond, or a rhombus. If it had four right angles, it would be a square.
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
A rectangle has four right angles too.
a square is a quadrilateral with four right angles. your welcome
It doesn't have to, but it can. A trapezoid is any shape in which there is a pair of parallel sides. This means that a square can be classified as a trapezoid. But notice that a four-sided shape can never have ONLY three 90° angles. The sum of angles of a four-sided shape is 360--this means that if you have three 90° angles, then the remaining angle must be 360-3(90) which is 90°, giving you four right angles. * * * * * No you cannot. As indicated in the second paragraph of the above answer, three right angles implies that all four angles are right angles and that makes the figure a rectangle (or a square).
