Answer:
An acute angle is an angle that measures less than 90 degrees. A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle.
An acute angle is any angle smaller than 90 degrees. A right angle is an angle that measures 90 degrees.
Like a reclining car seat, an obtuse angle has a measure of greater than 90 degrees.
