Best Answer

If available, a protractor or a right drawing triangle can be used. If restricted to ruler and compass, a right angle can also be constructed to a given line segment by drawing a circle, with a radius less than the length of the line segment but more than half that length, with each end of the line segment as a center and connecting the two points of intersection of the two circles above and below the line. The line connecting to two intersections of these circles will form as right angle to the line segment.

What is used to measure a angle?

the unit used to measure angle is degree. It is also measured in radians.


When you use the protractor do you use the top numbers or the bottom numbers?

You use both. An acute angle [ /_ or _\] is less than 90 degrees - directly on top. An obtuse angle is [ \_ or _/ ] is greater than 90 degrees. You use both. An acute angle [ /_ or _\] is less than 90 degrees - directly on top. An obtuse angle is [ \_ or _/ ] is greater than 90 degrees. You use both.

How you can tell when a angle is 200 degrees?

There are special angle-measuring instruments which you can use to measure the angle.


What is the measure of the third angle of a triangle if one angle measures 50 degrees and the other measure 85?

To find the measure of the third angle of a triangle, you can use the fact that the sum of all three angles in a triangle is always 180 degrees. So, if one angle measures 50 degrees and the other measures 85 degrees, you can subtract their sum from 180 to find the measure of the third angle. Therefore, the third angle would measure 180 - 50 - 85 = 45 degrees.


Can you make a supplementary angle out of 3 angles?

you can use up to 2 angles in a supplementary angle. Just find 2 angles to fit into 180 degrees.

What is it called when an angle goes past 360 degrees?

There is not a special name. You simply use the name for the angle which is left after you subtract 360 degrees from the angle.
