it wouldn't be a rhombus if it had a right angle.
No. Except for the case of a square (a special case of rhombus), a rhombus will have 2 congruent acute angles, and 2 congruent obtuse angles. The square has 4 right angles. In fact, every quadrilateral will have either all 4 angles equal to right angle (square and rectangle), or will have at least 1 obtuse angle (also at least 1 acute).
A rhombus is any four-sided figure whose sides are equal. A square is any rhombus with a right angle in it.
quadrilateral with no right angle * * * * * More specifically, a rhombus.
It doesn't have to, but it can. If it has one right angle, then it has four of them, and it's also a square.
A rhombus is a quadrilateral in which all of the sides are of equal length, It is an equilateral quadrangle. If any angle of an equilateral quadrangle is a right angle, then all its angles are right angles. It is also a square. All squares are rhombuses. Some rhombuses are squares. A rhombus is a parallelogram with 4 congruent sides. A square is a rhombus with 4 congruent angles.
no
A rhombus which has at least one angle a right angle (i.e. a square which is a special type of rhombus)
No. A rhombus is only a square if the rhombus contains at least 1 right angle.
No, a square is a four sided polygon with all it's sides the same length and where each angle is a right-angle. A rhombus may or may not have right angles. So while a square is a rhombus, a rhombus is not necessarily a square.
A rectangle (or square).
No. Except for the case of a square (a special case of rhombus), a rhombus will have 2 congruent acute angles, and 2 congruent obtuse angles. The square has 4 right angles. In fact, every quadrilateral will have either all 4 angles equal to right angle (square and rectangle), or will have at least 1 obtuse angle (also at least 1 acute).
square
A rhombus is a(n) equilateral parallelogram. A square is forming a right angle.
It can be, but it doesn't have to be. A rhombus is only a square if it has a right angle at one of its corners. Otherwise it's not.
A rhombus does not have four right angles. A square has four right angles, as does a rectangle.
No. That word is already taken. The square is a rhombus with a right angle.
a rhombus is not a square even though it has four side and four shape because it has no right angle.
