How do you draw an angle step by step?

How do you draw an angle step by step?

Solution:

1. Draw a straight line AB.
2. Place a dot at B.
3. Place the centre of the protractor at B and the baseline of the protractor along the arm BA.
4. Find 60º on the scale and mark a small dot at the edge of the protractor.
5. Join the vertex B to the small dot with a ruler to form the second arm, BC, of the angle.

How do you draw a 120 degree angle with a protractor?

Let us draw an angle EFG measuring 120°. Draw a ray EF. Place the protractor over EF such that the baseline of the protractor coincides with EF and the midpoint of the baseline coincides with point F. Read markings on the outer semicircle of the protractor and mark point G on 120°.

How do you calculate an angle without a protractor?

How do you draw a 110 degree angle with a protractor?

Answer

1. Draw a line segment PQ.
2. Keeping your compass wide open with the same length, draw an arc S on AB.
3. Bisect the 60° angle and name the point of intersection as J.
4. Join the arc J to A, which will give Angle JAB which is equal to 20°.
5. Now draw a perpendicular line AD on line segment PQ from point A.
6. Angle JAB = 20°

What type of angle is 110 degrees?
