All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.

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.)
Scalene or Acute triangle
The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.
acute
Acute angles are ones which measure less than 90 degrees.
Acute angles
A heart is not technically a geometric shape, but it depends on how you draw a heart. If the angles measure less than 90 degrees, they are acute angles.
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.
An acute angle is greater than 0 but less than 90 degrees
acute angles.
An acute triangle.
There aren't any acute angles in a square because an acute angle is less than 90 degrees. however, there are 4 right angles in a square. (which by the way a right angle is a measure of exactly 90 degrees)
Acute angles measure greater than 0 degrees and less than 90 degrees. Obtuse angles measure greater than 90 degrees and less than 180 degrees.
