How do you construct 45 degrees angle?

An angle of 45 degrees can be constructed by bisecting a right angle with a pair of compasses and a straight edge or merely using a protractor.


How do you draw 45 degree angle using ruler and compass?

Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle


Is it possible to construct angle 45 With the help of a ruler and a compass?

Yes. First draw a perpendicular (90 degrees) and then bisect the angle.


How can you construct 135 degree angle only with a scale and compasses?

Construct a perpendicular line that intersects a horizontal line at 90 degrees and then bisect the vertical line with the horizontal line will give an obtuse angle of 135 degrees because 90 degrees+45 degrees = 135 degrees


Is 45 degrees a reflex angle?

no a reflex angle is 145


Is a 45 degree angle an oblique angle?

An oblique angle is any angle not 90 degrees or a multiple of 90 degrees. So 45 degrees is an oblique angle. A 45 degree angle is also an acute angle (anything less than 90 degrees).

According to the law of reflection if the angle of incidence is 45 degrees what is the angle of reflection?

If the angle of incidence is 45 degrees, then the angle of reflection will also be 45 degrees. This is because the angle of incidence is always equal to the angle of reflection according to the law of reflection.


If the angle is 45 degrees what is the angle of reflection?

it will become 45 degree


Half of a right angle is how many degrees?

a right-angle is 90 degrees so half that 45 degrees your answer is 45 degrees
