# Can a rhombus have a 90 Angle?

This depends to some extent on context.

A rhombus is a parallelogram with all sides equal. On this basis a rhombus with 90 degree angles is just a square. Some authorities insist on defining a rhombus as not containing any right angles.

An angle in a rhombus can be any value less than 180 degrees. However, if the angle is 90 degrees, the rhombus becomes a square.

No. in a rhombus the angles are not 90 degrees. also in a parallelogram they are not 90 degrees

Both have all four sides the same length. A square has all 4 corners at 90&deg;, whereas a Rhombus can be leaning over (any angle) ._____ /....... /... Rhombus -------

A square is a rhombus with a right angle (90 degrees) at one corner.Note:That means that all four angles will be right angles, but in order to prove thatyour rhombus is a square, it's only necessary to prove that one angle is.

There is no such thing as an "angle rhombus". The opposite angles of a rhombus are equal, adjacent ones are supplementary.

every square is a rhombus because the opposite sides of a square are always parallel. Since every angle in a square is 90&deg; the angle between opposite sides is 180&deg; making them parallel

A rhombus which has at least one angle a right angle (i.e. a square which is a special type of rhombus)

Properties of rhombus that square has :- * All sides are equal. Properties of rectangle that square has :- *Each angle is 90 degree. *Diagonals are equal.

A rhombus is not an angel. One angle of a rhombus can have any value in the range (0, 180) degrees. The opposite angle is the same, and the other two are supplementary.

Any rhombus that does not have a right angle

That's called a "rhombus".If one of the angles inside it happens to be a right angle (90 degrees), then it's called a "square".

A rhombus has four sides of equal length; all angles add to 360 degrees. The special case of a rhombus is a square when not only all sides are equal abut also all angles are equal. Each angle is a right angle, 360/4 = 90 degrees. No other rhombus has equal angles

Any shape which has an angle can have an angle bisector.

The diagonals of a rhombus intersect each other at 90 degrees

Infinitely many. The smaller angle of a rhombus can take any value in the range (0, 90] degrees. Also, the length of the sides can be increased or decreased to any value.

depending if its a rhombus or so if it was a rhombus yes

Not normally but the nearest shape to a square without right angles is a rhombus

A rhombus may be a square or just a rhombus (a rhombus is merely called a rhombus when there are no 90 degree angles).

No. A rhombus is only a square if the rhombus contains at least 1 right angle.

An angle of 90 degrees is normally called a right angle.An angle of 90 degrees is a right angle

&lt;90 is an Acute angle =90 is a Right angle &gt;90 is an Obtuse angle
