an obtuse angle
Any polygon can have a right angle. A right angled triangle is an example.
Any polygon can have one right angle, for example, a right angled triangle.
a right angle is exactly a 90 degree angle. for example, there are 4 right angles on a square, the corners are right angles. like the edges on papers that is a right angle. an oblique line is smaller than a right angle.
if you are doing proof statements...there is converse which is where you flip the statement around so if the statement would be IF a angle measures 90 degrees, THEN the angle is a right anlge. The converse would be IF a angle is a right angle, THEN it is 90 degress. THE COUNTEREXAMPLE would be if the statement was false you would say or show a picture of something defining that statement
You use the points of the vertex and on the two sides. For example a right angle with a vertex of A and two sides B and C. would be Angle BAC

Because then it would not be a right angle. A right angle is 90 degrees. It is straight up and to the right.
90 degrees make a right angle. A corner of a piece of paper is an example. :)
An angle would only be a right angle if it was equal to 90 degrees. Anything less than that would be an acute angle and anything more would be obtuse.
