Angular Comparison: Determining the Greater Angle in Geometric Analysis

Question

Indicates which angle is greater

00:00 Which angle is larger?

00:03 According to the drawing, we can see that the left angle is larger

00:06 And this is the solution to the question

Answer B is correct because the more closed the angle is, the more acute it is (less than 90 degrees), meaning it's smaller.

The more open the angle is, the more obtuse it is (greater than 90 degrees), meaning it's larger.
