Suppose the rhombus is ABCD.
Consider the triangle ABC, whose area will be 40/2 = 20 sq cm.That is, 0.5*AB*BC*sin(B) = 20
sin(B) = 40/225 = 0.1777... recurring.
Therefore B = arcsin(1.777...) = 0.1787 or 2.9629 radians or equivalently, 10.24 or 169.76 degrees.
A rhombus has four congruent sides. The angles don't matter, but if they're right angles, then the rhombus is a square.
Both have sides of equal length so that a square is also a rhombus. But a the angles of a rhombus need not be right angles so it may not be a square.
No if it is a Square the has 4 angles and 4 sides than it could not be a Rhombus
No. Any square is also a rhombus, but the reverse is not true. A rhombus is a parallelogram having all four sides equal. A square is a rhombus in which all the angles are right angles.
Yes, a square is a rhombus, but a rhombus is not a square. Yes, a rhombus has four sides of equal length. A square is a rhombus with four right angles.
A rhombus has 4 equal sides. Its angles can be right angles, but don't have to be. A square is a type of rhombus.
A rhombus has four congruent sides. The angles don't matter, but if they're right angles, then the rhombus is a square.
A rhombus just needs to have its sides equal, but a square has to have both its sides and angles equal. A square is a rhombus, but you can't say a rhombus is a square. So the answer is no.
Both have sides of equal length so that a square is also a rhombus. But a the angles of a rhombus need not be right angles so it may not be a square.
A rhombus can be a square, but not necessarily.A square is always also a rhombus.A rhombus has 4 equal sides with opposite sides parallel and opposite angles equal.A square has 4 equal sides with opposite sides parallel and all angles 90o.
A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.
No if it is a Square the has 4 angles and 4 sides than it could not be a Rhombus
A square or a rhombus. A rhombus does not have 4 congruent angles as a square does. It's always a rhombus. And, depending on the angles, it could also be a square. (This definition treats the square as a special case of the rhombus.)
A rhombus.
NO!!! It can be a Rhombus. Square ' 4 equal sides and four angles at 90 degrees. Rhombus' 4 equal sides, but no angles at 90 degrees.
No. Any square is also a rhombus, but the reverse is not true. A rhombus is a parallelogram having all four sides equal. A square is a rhombus in which all the angles are right angles.
A rectangle is a square if all sides are the same length. A rhombus is a square if all angles are right angles (90o).
