Comparing Angular Measurements: Which Angle Has Greater Magnitude?

Question

Which angle is greatest?

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

In drawing A, we can see that the angle is more closed:

While in drawing B, the angle is more open:

In other words, in diagram (a) the angle is more acute, while in diagram (b) the angle is more obtuse.

Remember that the more obtuse an angle is, the larger it is.

Therefore, the larger of the two angles appears in diagram (b).
