Step-by-step explanation:
If you know, the sine. You must find the cos ratio, using the Pythagorean trig theorem.
Next, you use the half angle identity for sin
Example.
We must find
First, use the Pythagorean identity
Now use the half angle identiy
So the answer for our example is 1/2
So squares have 4 congruent sides. When you plot the points (0,0) and (0,5) the side length is 5 units. We can then take 5+5+5+5 and know the perimeter is 20 units.
