Yes. An acute triangle has three angles that individually are less than 90 degrees. Remember you can add the internal angles together in a triangle and they will always add up to 180 degrees.
It is called Acute triangleIn an acute triangle, all angle are less than 90 degrees, so all angles are acute angles.
Acute - less than 90 degrees Right - exactly 90 degrees Obtuse - more than 90 degrees but less than 180 degrees
Angles greater than 90 but less than 180 degrees are obtuse angles Angles greater than 180 but less than 360 degrees are reflex angles
Angles are measured in degrees, minutes and seconds Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
