A 60 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
A right angle triangle has one 90 degree angle and two acute angles
A right angle.
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
No. An octagon is a 2-dimensional closed polygonal shape: it is NOT an angle.
Any polygon can have a 40-degree angle. It doesn't have to, but it can.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.
Any polygon can have a 130-degree angle. It doesn't have to, but it can.
Which shape represents a 119˚ angle?
Acute
A 60 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
A 60 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
Providing that it is a regular 15 sided polygon then each interior angle will be 156 degrees
An angle is not a closed shape and so does not have a perimeter.
A 5 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
a 90 degree angle
140 degrees
