Select your language EnglishSpanish Angle sum and difference identities express trigonometric functions of sums of angles α ± β in terms of functions of α and β. Using the sum and difference formulas allows us to...

Select your language EnglishSpanish A right triangle is a polygon with three sides that has one angle (α) that measures 90° which is the largest angle of the right triangle. If we add all...

Select your language EnglishSpanish The hypotenuse of a right triangle (or right-angled triangle) is the side opposite its right angle. It is the longest side of a right triangle. We can find the hypotenuse...

Select your language EnglishSpanish Every triangle has lines (also called cevians) and points that determine a number of important elements. There are many different constructions that find a special point associated with a triangle,...

Select your language EnglishSpanish The area of a scalene triangle can be calculated using Heron’s formula if all its sides (a, b and c) are known. It could also be calculated if a side...

Select your language EnglishSpanish The area of an isosceles triangle is calculated from the base b (the non-repeated side) and the height (h) of triangle corresponding to the base. The area is the product...

Select your language EnglishSpanish Geometric mean (or mean proportional) appears in two popular theorems regarding right triangles. The geometric mean theorem (or altitude theorem) states that the altitude to the hypotenuse of a right...

Select your language EnglishSpanish The equilateral triangle has all three sides equal, so its perimeter will be three times the length of one of its sides (a). Download this calculator to get the results...

Select your language EnglishSpanish Some classical triangle centers are: Centroid (G) Orthocenter (H) Circumcenter (O) Incenter (I) Centroid of a Triangle The centroid of a triangle (or barycenter of a triangle) G is the...
