Area formula quadrilateral?
If it is a cyclic quadrilateral, meaning that it can be inscribed in a circle, then you can use the formulawhere S is the semiperimeter (half the sum of all the sides) and a, b, c, and d are all side lengths. If it is not a cyclic quadrilateral or you are unsure if it is or not then use the formula:where S is the semiperimeter (half the sum of all the sides) and a, b, c, and d are all side lengths and A and B are the angle measures across from side lengths a and b.hope this helps
Is a pentagon a quadrilateral?
No, a quadrilateral must have 4 sides. If it is a proper quadrilateral it must have 4 sides of equal length but if it is an irregular quadrilateral it must have 4 sides but not have equal sides. An example of a quadrilateral could be a square. A pentagon on the other side must have 5 sides.
Can a quadrilateral shape have curved side?
no because a quadrilateral has straight sides if it were curved it wouldn't be a polygon because polygons must have straight sides
