The law of sines states that the ratios of the side lengths to the sines of the opposite angles are all equal to the diameter D of the triangle’s circumcircle:a/sin a = b/sin b = c/sin c = D.The law of cosines draws a relationship between the squares of a side length and ...
An equilateral triangle also has three equal angles. The altitude of an equilateral triangle is (1) where is the side length, so the area is (2) The inradius , circumradius , and area can be computed directly from the formulas for a general regular polygon with side length and ...
Does a triangle has no right angles? A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles. A triangle with three congruent angles? A triangle with three congruent angles Can a tri...
