![]() How can we refine our approximation to make it better? The key to this section is this answer: use more rectangles. This is obviously an over–approximation we are including area in the rectangle that is not under the parabola. We can surround the region with a rectangle with height and width of \(4\) and find the area is approximately \(16\) square units.

What makes a rectangle special is the fact that all of its angles are. Rectangles are similar to parallelograms, so opposite sides are congruent and parallel. The following Venn Diagram shows the inclusions and intersections of the various types of quadrilaterals. Rectangle: A parallelogram with a right angle. Venn Diagram of Quadrilateral Classification ![]() Quadrilateral is a four-sided polygon that has no congruent sides. Which of the following figures satisfy the following properties - All sides are congruent. Some textbooks say a kite has at least two pairs of adjacent congruent sides, so a rhombus is a special case of a kite.) Is a quadrilateral with exactly two pairs of adjacent congruent sides. Is a trapezoid whose non-parallel sides are congruent. in America, trapezium usually means a quadrilateral with no parallel sides.) A rectangle is a four-sided polygon with opposing sides that are parallel and equal in length. (There may be some confusion about this word depending on which country you're in. Is a quadrilateral with exactly one pair of parallel sides. On the other hand, not all quadrilaterals and parallelograms are rectangles.Ī rectangle has all the properties of a parallelogram, plus the following:Ī rhombus has all the properties of a parallelogram, plus the following:Ĭan be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent sides and four right angles. ![]() Is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. Is a quadrilateral in which both pairs of opposite sides areĪ parallelogram also has the following properties: There are many special types of quadrilateral. ![]()
