WebIn geometry, an equilateral triangle is a triangle whose all three sides are of equal length. The sides of an equilateral triangle are congruent, which means that all sides are of equal length. All the interior angles are equal (60 degrees) too. The term equilateral is made up of ‘equi,’ which means equal, and ‘lateral,’ which means side. Web2 days ago · You know the lengths of all the sides but none of the angles. Rearranging the cosine rule equation gives the length of one of the sides. c = a2 + b2 - 2 ab cos C. Rearranging the equation: C = arccos ( ( a2 + b2 - c2) / 2 ab) The other angles can be worked out similarly. The cosine rule.
