Classify AFD: Rays and Angles.

∠AFD is an obtuse angle.

∠CFE is a right angle.

Acute angles: ∠AFB, ∠BFC, ∠DFE.

Solution:

An angle which measures less than 90° is called acute angle.

An angle which measures exactly 90° is called a right angle. It is denoted the by symbol "L".

An angle which measures more than 90° is called an obtuse angle.

In the given figure,

∠AFD is an obtuse angle.

∠CFE is a right angle.

Acute angles in the figure is ∠AFB, ∠BFC, ∠DFE.
