Interesting lines are the perpendicular bisectors, the angle bisectors, the median lines What interesting lines exist on triangles? The following formulae hold:įurthermore, for three sides a,b,c and angle alpha opposing of a:

With the help of a free angle finder calculator, you can easily find angle of triangle in a fraction. The sides and angles can be calculated by using sine and cosine. These angles differ for every different types of triangles. The area can be calculated as (side*height)/2 for any side and the corresponding height. What calculations can be done in a triangle? The height is the distance beween one side and the opposing corner. Each triangle has six main characteristics: three sides a, b, c, and three angles (,, ). But for example, if you got two sides and the height on one side, there is more than one possible triangle with those lengths. Triangle calculator The calculator solves the triangle specified by three of its properties. It is also determined by two angles and one side, ord by two sides and the angle between those sides.Ī triangle can also be determined by three other values. The sum of all interior angles of a triangle is always 180 degrees.īy what information is a triangle uniquely determined?Ī triangle is always determined by its three side lengths. the angle between the sides ending at that corner.
In every corner, there is an interior angle, i.e. The following formulas are right in equations:Ī triangle has three sides and three corners.
