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°, 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.
How many acute angles does a right triangle have?
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
How many diagonals can be drawn from one angle of a polygon with 64 sides?
64 sides = 64 angles From one angle you can draw (64 - 2) diagonals = 62. Lines from an angle to the immediately adjacent angles are sides, not diagonals.
How many degrees is a obtuse triangle?
An obtuse angle is an angle measuring between 90 and 180 degrees
How many lines for symmetry does a right angle triangle have?
None, unless it's also isosceles (1.e. 45 degrees for the other two sides).
