acute-angled triangle
An angle that measures between 0 and 90 degrees is an acute angle.
Obtuse angle
74 degrees
90 degrees and 78 degrees since one of the angles must be 90 degrees. We have 90+32=122 which is the second angle. Now the sum of the angles is 180 so 180-122=78 which is the third angle.
An angle that measures 210 degrees is a reflex angle.
