Question

What is special about a 30 60 90 triangle?

Answer 1

A 30-60-90 triangle is special because of the relationship of its sides. Also It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.

Hope this helps. :)

Answer 2

30= X. 5
90= 2x. 2(5)=10
60=x√3. 5√3

For example if the 30 ° is 5 then the 90 is 2(5)=10 the 60 is 5 √3
