Which of these is an acute
angle? Angle 𝐴, angle 𝐵, or angle
𝐶.
In this question, we have to
identify the acute angle. It can’t be angle 𝐵 because it’s a
right angle. This is the symbol we use to show a
right angle. We need to use our knowledge of
angles to help answer this question. We know that an acute angle is less
than a right angle. Does angle 𝐴 or angle 𝐶 measure
less than a right angle? We could use a right-angle measure
to help. Angle 𝐴 measures less than a right
angle. The angle which is an acute angle
is angle 𝐴 because it measures less than a right angle. Angle 𝐵 is a right angle, and
angle 𝐶 is greater than a right angle. Angle 𝐴 is an acute angle.
