TheLaw of Sinesdescribes the relationship between the sides and angles of oblique (scalene) triangles. sin(α)/a=sin(β)/b=sin(γ)/c You can use the Law of Sines to solve for the angle or side of any triangle. All you need is one angle and the side opposite of that angle. ...
meaning that you can always find the value of one angle in a triangle if you know the other two. This task is made easier for special triangles such as the equilateral, which has three equal sides and angles and the isosceles, which...
The study of trigonometry involves the measurement of triangles' sides and angles. Trigonometry can be a challenging branch of math and is often taught on a similar level as pre-calculus or more advanced geometry. In trigonometry, you often have to calculate unknown dimensions of a triangle with...
Scalene triangle A scalene triangle is a triangle with three different side lengths, and three angles with different measurements. In other words, none of the sides of a scalene triangle are equal to one another, and none of its three angles have the same measurement. ...
A rectangle is a geometric figure in which all four angles are 90 degrees. So if you have a missing side and it is a true rectangle, then you know the missing angle is 90 degrees. However, you could be working with a rectangle that is slanted. This is kn
The key to using this formula well is understanding the other measurements of a circle, and how to apply this area formula to sectors and pieces of a circle. The angles of a circle are often measured in degrees or radians, and we just need to know how to use these measurements as a ...
Tips Euclidean distance is the distance between two points in Euclidean space. Euclidean space was originally devised by the Greek mathematician Euclid around 300 B.C.E. to study the relationships between angles and distances. This system of geometry is still in use today and is the one that ...
The proper name for what many people call a diamond shape is actually a rhombus -- a four-sided figure where every side is the same length and each opposite pair of angles is equal. Rhombuses show up in everything from kites to floor tiles and, depending
You can view the exterior angle of a polygon by extending one of the sides of a polygon and looking at the angle between the extension and its adjacent side. All polygons follow a rule that the sum of their exterior angles will equal 360 degrees. (Althou
In trigonometry, if the sides of a triangle are all different lengths (i.e. unequal sides), we can determine it to be scalene. This also means that the interior angles will all be distinct. TL;DR (Too Long; Didn't Read) The area of a scalene triangle with base b and height h is...
