Because a right angle is a right angle.
because a right angle is right and a left angle is wrong

140 degrees is an obtuse angleAn angle of 140 degrees would be called obtuse.
a right angle is a right angle
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
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".
because a right angle is right and a left angle is wrong
The right angle.
The side opposite the right angle of a right angle triangle is the hypotenuse
A right angle. i think it's a right angle
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;
