# How many right angles triangle has?

a triangle can have only one right angle because the sum of all the three angles of a triangle has to be 180. so if there are more than one right angles, the sum of the angles will exceed 180 and hence the plane figure will no longer be a triangle

# How many right angles does a right triangle contain?

A Right Angle Triangle contains one right angle. A right angle has a magnitude of 90 Ã‚Â° , or in radians (pi/2). A triangle has three angles forming the closed shape, the addition of which gives an angle of 180 Ã‚Â° , or pi radians. With two right angles, the addition of these alone gives 180 Ã…‚Â° (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 Ã‚Â° , and no triangle can have two of these angles a Right Angle Triangle must have exactly one right angle. (MORE)

# How many obtuse and acute angles can be in a right triangle?

In a right triangle, one of the angles is already given - 90 degrees. Since the angles of a triangle must add up to 180 degrees, the other two must always add up to 90, so that after you add the right angle, the sum is 180. So both of the other angles have to be less than 90. That is, they bot…h must be acute. So there can be NO obtuse angles in a right triangle. There are EXACTLY two acute angles in a right triangle.
