A full circle is 360 degrees, half of that, an arc, is 180. Half an arc, or a right angle, is 90 degrees.
Ever heard someone say "Wow, he did a complete 180" when someone changes their mind about something? This is where it comes from. If you are in a circle and turn around to face the exact opposite side of the circle, you have turned 180 degrees.
Anyway, the answer is 90 degrees.
A right angle is 90 degrees
There are 90 degrees in a right angle.
A right angle is exactly 90 degrees.
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
An obtuse angle can be any angle over 90 degrees and below 180 degrees (anything over that is a reflex angle)
It depends what angle, if it's a straight angle it is 180 degrees, but if it is a right angle then it's 90 degrees.
