Are there any trapezoids that are also rhombuses?
yes - all the rhombuses. By definition a trapezoid has two parallel sides, a rhombus also has two parallel sides - because both pairs of opposite sides are parallel. So all rhombuses are trapezoids (but not all trapezoids are rhombuses)
Are all rhombus similar?
No. In order to be similar, their angles must be equal. Rhombuses don't all have to have the same set of angles. All a rhombus needs is four equal sides. Different rhombuses can be "squished" by different amounts.
Why is a square a rhombus?
A rhombus is any four-sided shape where all four sides are of equal length. A square has four sides. Each angle needs to be a right angle, a 90o angle, or else it will look skewed. If a side is longer than another side, it will look either skewed or like a rectangle. So, a square is any four-sided shape that has sides of equal length, which makes it a rhombus according to the definition above. Not all rhombuses are square - because their sides are equal but not their angles - but all squares are rhombuses.
Are some squares rhombuses?
All squares are rhombuses. A square is a special case of a rhombus with adjacent sides at right-angles. yes, squares are rhombuses.
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Are all rhombuses parellelograms?
All rhombuses are parallelograms because to be a parallelogram you only have to have four sides and have opposite sides congruent.
Can a rhombus be a parallelogram?
All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.
What geometric has 4 sides?
squares, rectangles, rhombuses, and parallelograms all have four sides
Are all rhombuses triangles?
No - a rhombus has four sides, while a triangle has three.
Why are kites not rhombuses?
All four sides of a kite need not be the same length.
Do rhombuses have four equal sides?
yes
Do rhombuses have four congruent sides?
Yes
Why must rhombuses have one pair of congruent sides?
All four sides of a rhombus must be congruent. In order for it to have four equal sides, it must have two!
A quadrilateral whose opposite sides are parallel and opposite angles are congruent and that has four congruent sides is a?
this would be a rhombus. rhombuses are parallelograms (four-sided shapes with opposite sides parallel) that have all equal side lengths. squares are included as rhombuses.
Why can't a rhombus have four congruent sides?
Rhombuses do have equal sides.
Why are all rhombuses parelllelagrams?
Because they are both four sided quadrilaterals with opposite parallel sides.
What do rhombuses and rectangles have in common?
Four sides, two pairs of parallel sides
