Can a right triangle have a 140 degree angle?
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.
Why is a right angle sometimes called a right angle?
Because a right angle is a right angle.
What is an right angle right angle-an angle that has a?
Assuming your question is what makes a right-angle, it is an angle of 90o .
Why is there a right angle but not a left angle?
because a right angle is right and a left angle is wrong
What is the external angle of a triangle?
360 degrees take away the internal angle
Is a hexagon a right angle?
no, the internal angles of a hexagon are 120 degrees and the external angles are 60 degrees.
What is the measure of each external angle of a square?
Each external angle of a square is 270o (360o - 90o).
Are the internal angle and external angle of a polygon supplementary?
yes.
A right angle has one right angle?
a right angle is a right angle

What is 90 angle degrees?
A right angle is an angle of 90 degrees.
What are external angles?
An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.
What is an right angle right angle-an angle that has a?
Assuming your question is what makes a right-angle, it is an angle of 90o .
A right angle is an angle that has a?
A right angle is a angle with 90o
What is the negation of angle a is a right angle?
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
Why is there a right angle but not a left angle?
because a right angle is right and a left angle is wrong
