Triangles are three-sided polygons that have three angles. In this article, we will explore different methods to calculate the angle of a triangle, including the use of trigonometric functions and ...

Type in the lengths of two sides of a right triangle. One in each of the boxes at the top. Then select if the missing side is the hypotenuse or a leg. You will also need to select the form that answer ...

A right triangle is a type of triangle where one of the three angles measures exactly 90 degrees. This angle is often referred to as the “right angle.” Because right triangles are such a fundamental ...

Given 3 values, calculate the remaining angles and lengths of a given triangle. This method works for any triangle (right, obtuse, or acute) rather than just right triangles as in the standard a^2 + ...

As the numbers are known on the opposite and the hypotenuse, then we look for the ratio which uses both these sides (SOH CAH TOA). That ratio is the sine ratio. \(\sin (x^\circ ) = ...

Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...
