The line at right angles to a surface?
A line with equal angles from a surface is referred to as being normal
What is a 180 degrees angle called?
A straight angle also known as a line
What is a angle with a measure of 180 degrees?
It is called a straight angle.
What does an obstuse angle measure?
An obtuse angle is any angle which measures between 90 degrees (that is, a right angle), and 180 degrees (that is, a straight line).
How many right angles are needed to form a straight angle?
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
What is the line that makes an 90 degrees with a surface is called what?
It is called a right angle.
What does a straight angle makes?
A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees
What type of angle makes a straight line?
180 degrees -- a straight angle
What angle that makes a straight line?
90 degrees
What is a definition of Perpendicular?
Perpendicular is a line drawn over a surface at an angle of 90 degrees.
What is the angle formed by the line perpendicular to a surface and the direction in which a reflected ray moves?
0 degrees
The line at right angles to a surface?
A line with equal angles from a surface is referred to as being normal
What is the degrees og a straigh line angle?
A straight line has an angle of 180 degrees.
What is 360 degrees angle called?
When the original line makes a complete revolution, the formed angle is called a perigon, or round angle.
What are the angle of reflection and the angle of incidence?
when the ray of light coincides on the surface, it makes an angle with the normal ( imagininary line perpendicular to the surface) this angle is called angle of incidence. When the light reflects backs after striking the surface it makes angle with the normal, this angle is called angle of reflection.
The angle of incidence is the angle between the incident ray and the line to the surface?
Line perpendicular to the surface.
An angle of 180 degrees is?
An angle of 180 degrees is a straight angle, a straight line.
