equilateral isosceles triangle area formula calculator allows you to find an area of different types of triangles, such as equilateral, isosceles, right or scalene triangle, by different calculation formulas, like Geron's formula, length of triangle sides and angles, incircle or circumcircle radius....
intersect other than at these vertices. The sum of the interior angles is (n–2) × 180° fornsides; the sum of the exterior angles is 360°. Aregular polygonhas all its sides and angles equal. Specific polygons are named according to the number of sides, such as triangle, pentagon, ...
There is a special type of triangle, the right triangle. In that case, the base and the height are the two sides that form the right angle. Then, the area of a right triangle may be expressed as: Right Triangle Area = a × b / 2 Circle area formula The circle area formula is one...
