WebA 30-60-90 right triangle is a special right triangle in which one angle measures 30 degrees and the other 60 degrees. The key characteristic of a 30-60-90 right triangle is that its angles have measures of 30 degrees (π/6 rads), 60 degrees (π/3 rads) and 90 degrees (π/2 rads). The sides of a 30-60-90 right triangle lie in the ratio 1:√3:2.

WebMar 17, 2024 · What are the 30 60 90 triangle rules? The most important rule to remember is that this special right triangle has one right angle, and its sides are in an easy-to-remember consistent relationship with one another - the ratio is a : a√3 : 2a. WebFeb 11, 2024 · All that you need are the lengths of the base and the height. In a right triangle, the base and the height are the two sides that form the right angle. Since multiplying these to values together would give the area of the corresponding rectangle, and the triangle is half of that, the formula is: area = ½ × base × height.
