A rhombus is an oblique-angled equilateral parallelogram, but not a square.
Explanation: Oblique-angled means that there can be no perpendicular angles like in a square.
Two parallel sides is part of the definition for a rhombus.
A parallelogram with four equal sides.
A rhombus is a square tilted on it's side. Or a rhombus is a diamond, or the sandbox looked like a rhombus.
The answer depends on which definition of trapezoid (or trapezium, outside of North America) is used.Some mathematicians define a trapezoid as any four-sided figure with at least one pair of parallel sides. Using that definition, a rhombus is a special type of trapezoid because a rhombus is a figure with two sets of parallel sides.Others are more strict, using the name trapezoid only for four-sided figures with exactly one pair of parallel sides. By this definition a rhombus is not a trapezoid.
The definition of a parallelogram is that it has four sides, the opposite sides are congruent and parallel, and opposite angles are congruent. This includes rectangles, squares, rhombuses, etc.The definition of a rhombus states that it is a parallelogram, but more specifically that all sides are congruent.So a rhombus is a parallelogram, but not all parallelograms are rhombuses.
A square is a rhombus by the modern definition of rhombus as a quadrilateral with four equal sides. An old definition of rhombus added the clause that it is not a square.
A rhombus is always a parallelogram, by definition.
Yes, the root word of "rhombus" is from the Greek word "rhombos," meaning something that spins around or spins in a circular motion.
A rhombus by definition has four sides, and a triangle has only three. So, a triangle is never a rhombus.
A rhombus is a quadrilateral whose four sides all have the same length.
Yes, by definition.
A rhombus is NOT a regular polygon, since the angles need not be equal. A rhombus does have four equal sides, by definition.
A rhombus, by definition, must be equilateral. Therefore, an isosceles rhombus cannot exist and so it cannot be a parallelogram.
Two parallel sides is part of the definition for a rhombus.
A parallelogram with four equal sides.
No, by definition a rhombus has all angles equal, but they are not right angles. A square is a type of rhombus with four right angles.
Look at the definition of a rhombus. A square fulfills all parts of the definition.
