![]() The sum of the opposite angles is always 180 degrees in quadrilaterals such as trapezoids.In some quadrilaterals, such as rectangles and squares, opposite angles are congruent.In some quadrilaterals, such as kites and rhombi, opposite sides are congruent.In some quadrilaterals, such as parallelograms, opposite sides are parallel.A convex quadrilateral has all its interior angles less than 180 degrees, and a concave quadrilateral has at least one interior angle greater than 180 degrees. A quadrilateral can be concave or convex.The sum of the interior angles of any quadrilateral is always 360 degrees. These sides can either have equal or unequal lengths. ![]() However, here are some of the common properties of all the quadrilaterals: And often, the properties depend on the type of quadrilaterals. Intersecting quadrilaterals can have unique and complex properties compared to convex and concave quadrilaterals, such as unequal opposite sides, diagonals that do not intersect inside the shape, and different angles formed by the intersection of sides. When two sides of the quadrilateral cross, they form an intersection point where the sides meet. Intersecting QuadrilateralĪn intersecting quadrilateral is a polygon with four sides and four angles, but at least one pair of its sides cross each other instead of being parallel. Concave quadrilaterals can have properties that differ significantly from convex quadrilaterals, such as non-parallel opposite sides and diagonals that do not always intersect inside the shape. This inward-pointing vertex causes the polygon to have a hollow or “cave-like” shape. Concave QuadrilateralĪ concave quadrilateral is a polygon with four sides and four interior angles, but at least one of its angles measures more than 180 degrees, which means that at least one of its sides is bent inward or “caving in.” In a concave quadrilateral, at least one of the vertices points inward. Additionally, a convex quadrilateral has two diagonals that intersect inside the shape, dividing each other into two equal parts. Convex quadrilaterals have outward-pointing vertices, and their opposite sides are parallel. If all the angles inside the quadrilateral are less than 180 degrees and none of the sides is bent inward or “caved in,” the quadrilateral is considered convex. Here is how they are classified accordingly: Convex QuadrilateralĪ convex quadrilateral is a polygon that has four sides and four angles. You can classify quadrilaterals as convex, concave, or intersecting quadrilaterals based on shape and orientation. Convex, Concave, and Intersecting Quadrilaterals Kite: A kite is a quadrilateral shape with two pairs of adjacent sides of equal lengths. Trapezoid: A trapezoid is a quadrilateral with a pair of parallel sides. Parallelogram: A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Rhombus: A rhombus quadrilateral has four equal sides, but only opposite angles are equal. Rectangle: A rectangle is a quadrilateral with four right angles, but only two parallel sides are equal in length. Square: A square is a quadrilateral with four equal sides and four right angles. Each one has its own rules and properties. There are many different types of quadrilaterals, some of which you already know. It is derived from the Latin words “Quadri,” meaning “four,” and “latus,” meaning “side.” The study of quadrilaterals falls under the branch of mathematics known as geometry and has applications in fields such as architecture and engineering. So, what is quadrilateral? It is a four-sided polygon, which means it is a geometric shape with four straight sides and four angles. The quadrilateral definition is quite simple. Whether you’re a math teacher or a parent who wants to teach your child about geometry, this article will offer insights and inspiration for the quadrilateral concept. Read on to learn about the world of quadrilateral shapes, their properties, classification, and applications in real-world problems. From a simple rectangle to a complex kite, these geometric shapes have different properties and characteristics that make them fun and exciting to study.
