Angles that measure less than 90 degrees are called acute angles. Right angles measure exactly 90 degrees and obtuse angles are greater than 90 degrees.
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
Only if their sum is greater than 90 degrees
Acute angles.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
Greater than 0 degrees but less than 90 degrees.
Acute angles are less than 90 degrees. Obtuse angles are greater than 90 degrees. Right angles are 90 degrees.
An acute angle measures 87 degrees
Acute angles are greater than 0 but less than 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees but less than 360 degrees
Acute angles are greater than 0 but less than 90 degrees
