No, not really. The two remaining interior angles have to add up to 90, since the sum of the angles in a triangle must total 180. The right angle means you have already used 90, so the remaining two must have a sum of 90. There is a more complex answer. Right triangles can have an external angle of 140. If angle A is 90 degrees, and angle B is 40 degrees, then angle C will be 50 degrees. The external angle at the extension of AB, through corner B, namely the extension of a ray from A through B, will create an angle with segment CB. It will be the sum of the measures of A and C: 140 degrees.
Because a right angle is a right angle.
Assuming your question is what makes a right-angle, it is an angle of 90o .
360 degrees take away the internal angle
because a right angle is right and a left angle is wrong
no, the internal angles of a hexagon are 120 degrees and the external angles are 60 degrees.
Each external angle of a square is 270o (360o - 90o).

yes.
a right angle is a right angle
An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right angle is a angle with 90o
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
360 degrees take away the internal angle
