Question

What is the correct classification for each given angle?

Answer 1

The answer to the question

Answer 2

The meaning of the options are:

• Acute: an angle between 0 and 90 degrees;
• Straight: and angle of 180 degrees;
• Right: an angle of 90 degrees
• Obtuse: an angle of more than 90 degrees

So, AFB is acute, because it's and angle of 48 degrees, between it's complementary to BFC and they for a right angle.

DFB is obtuse, because it's the right angle DFC plus the angle CFB

Finally, CFD is right (we can only deduce this by looking at the picture)
