Supplementary Angles Proof: Is Alpha + Beta = 180 Degrees?

Question

True or false?

$\alpha+\beta=180$

Video Solution

Solution Steps

00:00 Determine whether the angles add up to 180 degrees

00:03 The angles are on the same line and are intersected by the same leg

00:06 Therefore they are adjacent angles, adjacent angles add up to 180 degrees

00:10 This is the solution

Step-by-Step Solution

Given that the angles alpha and beta are on the same straight line and given that they are adjacent angles. Together they are equal to 180 degrees and the statement is true.

Answer

True
