The sides are in the ratio 1 : (1/2) : sqrt(3)/2, where sqrt denotes square root.
That these are the ratio of the sides of a right-angled triangle can be confirmed using Pythagoras' theorem:
1*1 = (1/2)*(1/2) + ( sqrt(3)/2 )*( sqrt(3) / 2 ) = ( 1/4 ) + ( 3/4 ) = 1
1/2 is the sine of 30 degrees.
sqrt(3)/2 is the sin of 60 degrees.
Remember this identity, it is very useful.

Definition of the 30-60-right triangle theorem?
90
In a 30 60 90 triangle an angle LM is 4 what is angle LN?
A "30 60 90 triangle" has that weird name because those numbers are its three angles. It can't have any angle of "4". If a triangle has an angle of '4', then it's not a '30 60 90 triangle'.
What is a 30-60-90 right triangle?
in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
What is the equations for a 30-60-90 triangle?
The answer depends on WHAT the equation is about.
How do you find the perimeter of a 30-60-90 triangle?
180
