Many shapes have a right angles. For example, a right angled triangle, square or rectangle all contain at least one right angle. Trapeziums may also contain right angles. Any irregular polygon may also contain a right angle.
None because it can only have 1 right angle and 2 acute angles to be a right angle triangle and the 3 angles add up to 180 degrees.
Since a triangle has 3 angles that total 180 degrees, it can have only 1 right angle. Since a triangle has 180 degrees and 3 angles, it can only have 1 right angle.
A right angle only has one angle.
A right angle is 90 degrees
A "right angle" is 90 degrees.
an obtuse angle has 2 angles. Obtuse angle: _/-acute / right
a cone doesn't contain any right angles fool !
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 can have at most 1 right angle, however depending on the triangle the may not be any.
2, obtuse and reflex angles are larger than right angles A straight angle is larger.
A right angle is 90 degrees and the 4 interior angles of a square and a rectangle are all right angles.
3 or 1. depending on which triangleImproved Answer:-Only one and the other two angles must be acute angles
The square has four right angles. The pentagon has two right angles.
The 7 types of angles are:acute angleright angleobtuse anglesupplementary anglestraight angle.complementary anglereflex angle
there are 4 angles and normally, there would be 2 angles that are smaller than a right angle Except of cause if the parallelogram is a square or a rectangle, all angles are equal to 90 i.e. right angle
Just the one and the other two angles are acute angles
A right-angle triangle will have one right-angle (90 degrees).
i think it has 1 right angle
A right angle is 90 degrees.
The arrowhead has zero right angles.
A right angle = 90o angle. So, number of right angles in a 720o shape = 720 / 90 = 8.
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
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 is a turn of 90 degrees.
