A square and a rhombus
Chat with our AI personalities
First of all, quadrilaterals are just shapes with 4 sides! The word "quadrilateral" comes from the Spanish word "cuatro" which means four. One shape that has all sides equal length and is a quadrilateral is a square. Another one is a rhombus. Because it has 4 equal sides that are the same length. That easy! I hope this helps!
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
No. This is only true of parallelograms.
If all the sides are different lengths, it can only be called a quadrilateral. In general, four sided two dimensional objects are called quadrilaterals. When all four sides are the same length it is a square if all four corners are right angles. Otherwise it is a rhombus. If the opposite sides are the same length, it is a rectangle if the four corners are right angles, otherwise it is a parallelogram. In all these cases, the opposite sides are parallel to each other. There is also the trapezoid, a quadrilateral with only one pair of parallel sides. If the opposite sides are the same length but not parallel. it is an isosceles trapezoid.
In general no. A regular hexagon has the same length on all sides. Also, there are other hexagons with the same length on all sides that are not regular.
