How do you work out angles on a straight line?
The angles on a straight line add up to 180 degrees. So x + y = 180. Therefore y = 180 - x.
What are angles on a straight line called?
A straight angle is also called a 'flat angle'. A straight angle pair is a set of two adjacent angles on a straight line that add up to 180° If ∠A + ∠B = 180°, then ∠A and ∠B form a straight angle pair (linear pair).
What does an angle on a straight line add up to?
Sum of angles on one side of a straight line
The sum of all the angles on one side of a straight line is always 180 degrees. For example, The sum of ∠1, ∠2, and ∠3 is 180 degrees.
