An obtuse angle is an angle measuring between 90 and 180 degrees

First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.

A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.

A Right Angle Triangle contains one right angle.A right angle has a magnitude of 90Â°, or in radians (pi/2). A triangle has three angles forming the closed shape, the addition of which gives an angle of 180Â°, or pi radians. With two right angles, the addition of these alone gives 180Â° (pi radians), and therefore the last angle has a null value. This is impossible and therefore leads to the conclusion that no triangle can have more then one right angle.As the definition of a Right Angle Triangle requires an angle of 90Â°, and no triangle can have two of these angles a Right Angle Triangle must have exactly one right angle.

A triangle has three internal angles and three external angles, for a total of six angles.
