when your using an angle ruler, otherwise known as the protractor, you start by lining up the line (located at hte center of the bottom area) with the point of the angle where the two lines of it meet. then you you line up the line with whatever number it would continue onto.
example: L is a 90 degree angle. if u lined up the part of it pointing upward with a number on the curved part of the protractor, it would point directly at 90.
My daughter in 5th grade would like me to mention that she answered this question, and i typed it here. she also gave the example.
use a protractor and a ruler
use trisection method
I generally use a pencil and ruler. To construct the right angle to draw it I also use compasses. To measure the right angle to draw it I also use a protractor.
A ruler. Add a line to make the angle into a triangle, measure the sides and use trigonometry.
To bisect an angle using a compass and ruler, start by placing the compass point on the vertex of the angle and drawing an arc that intersects both rays of the angle. Label the points where the arc intersects the rays as A and B. Next, without changing the compass width, place the compass point on point A and draw an arc inside the angle. Repeat this step from point B, creating two intersections of the arcs. Finally, use the ruler to draw a straight line from the vertex of the angle through the intersection of the two arcs, which will bisect the angle.
use a protractor and a ruler
Use a ruler
An angle ruler is a tool used to measuring angles like a protractor. An angle ruler is more accurate than a protractor.
i think you can use a ruler not sure
You don't always need a protractor to make an angle, just use a normal ruler.
use trisection method
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.
You angle a picture on pages by turning it a little bit but not to much or you will get a obtuse angle and make sure you use a ruler or something straight to balance it.
No, a ruler is used only to measure length, width or height. You must use a protractor in order to measure the degrees in an angle.
You cannot measure an angle using a ruler.
well an angle ruler is used to measure the interior angles of a shape or an agle period
