True or false?
An acute angle is smaller than a right angle.
The definition of an acute angle is an angle that is smaller than 90 degrees.
Since an angle that equals 90 degrees is a right angle, the statement is true.
True
What can be found in the following figure?
An acute angle measures less than 90 degrees, while a right angle measures exactly 90 degrees. Think of it like this: acute angles are 'sharp' and smaller than the corner of a square!
Yes! As long as an angle measures less than 90 degrees, it's acute. So 89.9°, 45°, 30°, and even 0.1° are all acute angles.
The order goes: acute (less than 90°) → right (exactly 90°) → obtuse (between 90° and 180°) → straight (exactly 180°).
Think of the word 'acute' as meaning sharp or pointed. Acute angles look sharp and narrow, like the tip of a pencil - they're smaller than the square corner of a right angle!
Yes! Compare the angle to a right angle (like the corner of a book or square). If your angle looks smaller and more pointed than that corner, it's acute!
