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.
There are many. For example, if A and B are the two acute angles, then A + B = 90 degrees or sin(A) = cos(B) or cos(A) = sin(B) or tan(A) = 1/tan(B)
None
A Right Angle Triangle contains one right angle.A right angle has a magnitude of 90°, or in radians (pi/2). A triangle has three angles forming the closed shape, the addition of which gives an angle of 180°, or pi radians. With two right angles, the addition of these alone gives 180° (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 90°, 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.
In a right triangle there is only one acute angles.
None. If there was a right angle then it would not be called an acute triangle.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
Two.
In an acute triangle, all three angles are acute.
there are three acute angles in an acute triangle, because there are three corners.
There are many possible shapes with two acute angles.
There are three acute angles in an acute triangle and they add up to 180 degrees.
none - it's an isoscelese triangle it doesn't have right angles. It has two equal angles (both acute) and one other andgle (also acute)
there are three acute angles in an acute triangle, because there are three corners.
Just 1 when its a right angle triangle and the other 2 angles are acute angles The 3 interior angles add up to 180 degrees
There are 2 acute angles with one 90 degree angle and the 3 angles add up to 180 degrees
