It could be an isosceles triangle, an isosceles trapezium, or miscellaneous polygons with no special name.
Parallelogram is a quadrilateral with opposite sides both parallel and equal in length - commonly known as a rectangle.
A parallelogram is a shape with opposite sides equal in length and parallel to each other. Examples of parallelograms are: rhombus, square, rectangle, and rhomboid.
The answer is irregular * * * * * That is not true. A rhombus is irregular but does have equal sides. Any shape with equal sides - other than an equilateral triangle - can be distorted so that its angles are not equal. That is enough to make it irregular, even though the sides remain of the same length. There is no specific name for such shapes.
A Scalene triangle has no sides of equal length.
The name of the shape is a quadrilateral.
It is usually a regular polygon that has equal sides.
An isosceles triangle has exactly two sides that are equal in length.
Square. By definition, its sides must all be equal.
Most quadrilaterals do not have opposite sides which are equal in length. Sadly, there is no special name for them.
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!
