An obtuse angle is an angle between 90 degrees and 180 degrees. A 180 degree angle is a straight horizontal line. So you can imagine that a 160 degree angle is almost but not quite horizontal.
Bigger than 90 (a right angle), less than 180 (a straight line).
put the protractor on the vertex and look up at the degree's and look belowacute angle =has a measure between 0 degree's and 90 degree'sright angle =has a measure of 90 degree'sobtuse angle = has a measure between 90 degree's and 180 degree'sstraight angle = has a measure of 180 degree'sthat's how you use a protractor to measure angles.
You would subtract 40 degrees from 180 degrees so it would look like this:180 degrees - 40 degrees = 140 degrees
180 - 12 = 168 degree angle
a line or straight angle
It is a reflex angle because it is greater than 180 degrees
An obtuse angle is an angle between 90 degrees and 180 degrees. A 180 degree angle is a straight horizontal line. So you can imagine that a 160 degree angle is almost but not quite horizontal.
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
It is a reflex angle which is greater than 180 but less than 360 degrees
It is an obtuse angle because it is greater than 90 but less than 180 degrees
Bigger than 90 (a right angle), less than 180 (a straight line).
Answer = A 180 degree angle is called a Straight Angle!!
Answer = A 180 degree angle is called a Straight Angle!!
180 degree angle
No, a 180-degree angle is called a straight angle.
180 degrees would look like a straight line if viewing it in the form of an angle. It is also defined as the exact opposite direction of the initial direction.
