The ratio of the sides follow the triangle ratio 1 2 √3 1 2 3 Short side (opposite the 30 30 degree angle) = x x Hypotenuse (opposite the 90 90 degree angle) = 2x 2 x Long side (opposite the 60 60 degree angle) = x√3 x 3Visit https//wwwmathhelpcom/geometryhelpIn this video, we use the 45°45°90° and 30°60°90° triangle formulas to find the misAn equilateral triangle can be bisected into two 30° 60° 90° right triangles The height bisects the base and one angle of the triangle, creating two triangles that are congruent 30° 60° 90° right triangles Therefore, you only need the length of one side or the height to be able to find the area of an equilateral triangle
