A straight angle is a half circle.
a line
a line or straight angle
A straight line passing through the point at which the angle is located.
A straight horizontal line intersected by a straight vertical line.
A straight angle is a half circle.
a line
A straight angle has 180 degrees. It is an angle that has sides in opposite directions from its vertex. A straight angle will look like a straight line.
a line or straight angle
A straight line passing through the point at which the angle is located.
Like __/ or \__. (in between a straight line and a right angle (perpendicular lines)
a bit wider than a right angle (90 degrees)
A straight horizontal line intersected by a straight vertical line.
It's a reflex angle and nearly looks like but not quite a straight line
A straight line of 180 degrees
They are just straight lines that is a 90* angle.
An obtuse angle is between 90o and 180o.90o is a right angle.Between 90o and 180o is an obtuse angle.180o is a straight angle.A right angle is like this (look at ray A):A^|||L-----------> exactly 90oA straight angle is this (look again at ray A):A 180o is flatFor an obtuse angle, the A should be somewhere between the places where A was in the right and the straight angles.
