Angle Comparison: Determining the Greater Angle in Geometric Analysis

Question

Indicates which angle is greater

00:00 Which angle is bigger?

00:03 According to the drawing, we can see that the angle is obtuse, meaning it's larger than 90

00:06 And this is the solution to the 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.
