Pi = 3.14159265358979

Sine of 45 degrees, pi/4 is a C Student 0.7071

Triangles – All angles add up to 180 degrees, pi radians

Google can convert 3.14159265358979 radians to degrees = 180 degrees

Key details 45 degrees is 1/4th of 180 degrees, 1/8th of 360 degrees

if 1 pi radians equals 180 degrees, 1/4th pi radians equals 45 degrees

Then 2 pi radians equals 360 degrees, and 1/2 pi equals 90 degrees

If 6*30 degrees = 180 degrees, then 1/6th pi radians = 30 degrees

if 3*60 degrees = 180 degrees, then 1/3rd pi radians = 60 degrees

30 degrees + 30 degrees = 60 degrees, 1/6th pi radians + 1/6th pi radians = 2/6th pi radians = 1/3rd pi radians

If 60 degrees plus 30 degrees = 90 degrees, and all angles of a triangle add up to 180 degrees, then 180 degrees – 90 degrees = 90 degrees
