an obtuse angle.
Do you go to cardinal hickey academy?
straight angle
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
It's a flat line. Or a line segment. Or a "half line" with one endpoint (the vertex of the 0 degree angle).
No. An obtuse angle is greater than 90o and less than 180o. A 180o angle is classified as a straight angle.
A 220-degree angle is classified as an obtuse angle because it is greater than 180 degrees but less than 360 degrees. Specifically, it is also considered a reflex angle, as it is more than 180 degrees and extends beyond a straight line. In a circle, it represents a rotation that goes beyond half a full turn.
A straight line is equal to a 180 degree angle.

A straight angle
A right/straight angle. An angle of 90 degrees or ½π radians.
A right angle.
No. An obtuse angle is greater than 90o and less than 180o. A 180o angle is classified as a straight angle.

An angle bisector is a line. A bisector is something that cuts something into two equal parts. The line passes through the angle dividing it into two equal parts and is called an angle bisector.
A right angle.
