If an exterior angle of a quadrilateral equals the opposite interior angle, then the quadrilateral is cyclic. The proof by contradiction of the first test is almost identical to …... If you want to aim at a unique quadrilateral, it is necessary (and sufficient) to know at least two angles on either end of the second side (middle of the three given sides). Otherwise, you …

**Trigonometry/Area of a quadrilateral Wikibooks open**

The area of a quadrilateral describes the surface of a two-dimensional shape. Area can be visualized as the number of tiles it takes to cover a floor or the amount of paint that a wall needs. To find the area of a quadrilateral, take careful measurements of the length, width and height of the shape and use the appropriate formula for the specific type of quadrilateral.... Lets do this! :D Alright! So first, you want to focus on that angle on the bottom left on the polygon. Because it is straight angle and you know that the angle adjacent to it is 180-x, that means that the angle of the polygon is x

**Brahmagupta's Formula for the Area of a Cyclic Quadrilateral**

Mathplanet. Menu Geometry / Area / The surface area and the volume of pyramids, prisms, cylinders and cones . The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold... For any other quadrilateral, divide the shape into two triangles, find the area of each and add them together. Related questions How do you classify the triangle given 2 cm, 2 cm, 2 cm?

### If an exterior angle of a quadrilateral equals the opposite interior angle, then the quadrilateral is cyclic. The proof by contradiction of the first test is almost identical to …

- Brahmagupta's formula provides the area A of a cyclic quadrilateral (i.e., a simple quadrilateral that is inscribed in a circle) with sides of length a, b, c, and d as where s is the semiperimeter Note: There are alternative approaches to this proof.
- If a quadrilateral is circumcyclic, i.e. such that a circle can be inscribed in it touching all four sides, then a+c=b+d. This is easily proved by noting that the lengths of …

- 29/05/2009 · Re: Working out the area of a quadrilateral It's not easy - I haven't been to school recently!! As far as I can work it out, if you square up everything by extending the lines to the points of intersection, you end up with a rectangle that is 5m x 4.35m (21.75m sq).
