Angle Comparison: Determining the Greater Angle in Geometric Analysis

Question

Indicates which angle is greater

00:02 Which angle is bigger?

00:05 Look at the drawing. The angle is obtuse, so it's larger than ninety degrees.

00:10 And that's the solution to our question.

Note that in drawing B, the two lines form a right angle, which is an angle of 90 degrees:

While the angle in drawing A is greater than 90 degrees:

Therefore, the angle in drawing A is larger.
