Quadrilaterals are shapes with four sides and four angles that can vary in complexity. They are categorized based on their sides and angles, with examples including squares, rectangles, rhombi, isosceles trapezoids, and parallelograms. Parallelograms and rhombuses are slanted shapes with only two congruent sides each, while other quadrilaterals like squares can have all congruent or no congruent sides.

1. Quadrilaterals

2. Quadrilaterals a shape with 4 shapes and 4 angles. It can be simple yet can be also be complex It comes in different shapes. Categorized by their sides and angles. Examples of which are square and rectangles. Include in the list are rhombus, isosceles.Parallelogram and trapezoid are also quadrilaterals. It can be concave and can also be complex. Other square have congruent side and other square has no congruent side.

3. Parallelogram has only 2 congruent side. Parallelogram and rhombus are slanted. The meaning of concave is curved like the inner surface of a sphere. The meaning of complex is composed of two or more parts. The rhombus has only 2 congruent side because it is slanted. The parallelogram has only 2 congruent side because it is slanted
