Acute Angles: Which statement correctly describes an acute angle?

• A. x > 90
• B. x < 90
• C. x = 90
• D. x ≤ 0

Answer: (B)

An acute angle is an angle that measures less than 90 degrees. So the statement that describes an acute angle is that x is less than 90. Think of a small, tightly opened corner, like 30°, 45°, or 60°. The other possibilities describe different kinds of angles: greater than 90 would be obtuse, exactly 90 is a right angle, and zero or negative measures don’t describe a real angle.
