How do you work out a 60 degree angle?

How do you work out a 60 degree angle?

Constructing a 60° angle

1. open the compass to the same dimensions as our original line.
2. place the point of the compass on one end of the line and draw an arc.
3. repeat this at the other end and the arcs should intersect where the tip of the triangle should be.

How do you construct a 45 degree angle without a protractor?

Answer: Follow the steps shown below.

1. Draw a line segment BC of any length.
2. Taking B as the center, construct a semicircle that bisects BC at point P.
3. From P, construct three arcs dividing the semi-circle into 3 equal parts that are 60º each.
4. Mark the points as x and y where the arcs bisect the semi-circle.

How do you construct a 60 degree angle with a ruler?

How do you make a 45-degree angle without a protractor or compass?

If you need to figure out a 45-degree angle and you don’t have a protractor handy, you can create a workaround. A 45-degree angle is half the size of right angle, which is 90 degrees. Working with a ruler and a square or other right angle substitute, you can make the angle without any special tools.

How do you make a 30 degree angle without a protractor or compass?

Here’s how to construct an angle ABC of 30 degrees. Then, to make construct the 60 degree angle, draw a straight line from point B to the point where your two arcs cross, which I will label X. We’ll now bisect this angle, or cut it in half, to make the 30 degree angle.

How do you construct a 60 degree angle?

How do you construct a 45 degree angle?

A 45 degree angle is the half of 90° angle. For its construction, you first construct a 90-degree angle as discussed above. Then, you bisect this angle. You get two 45 degree angles. Note: For constructing angles like 15 degrees or 22.5 degrees, you further bisect 30 degree angle and 45 degree angle respectively.

What tools do you need to draw a 30 degree angle?

This article has been viewed 140,893 times. To construct a 30-degree angle, you’ll need a compass, a straightedge, such as a ruler, and a pencil. Start by drawing a horizontal line and marking the left end “A” and the right end “B” to serve as the vertex of the angle.

How to draw a 30 degree angle with a compass?

How to Draw a 30 Degree Angle 1 Draw a ray AB. 2 Place the tip of the compass on A and draw an arc which cuts AB at some point (say X). 3 Place the tip of the compass on X and draw another arc… 4 Place the tip of the compass on Y and draw another arc (Arc Three) so as to cut Arc Two at a point… See More….

What is the double of a 60 degree angle?

A 120-degree angle is the double of a 60-degree angle. The steps for its construction are: Step 1: Draw a line segment. Mark the left end as point O and the right end as point B. Step 2: Take the compass and open it up to a convenient radius. Place its pointer at O and with the pencil-head make an arc which meets the line OB at say, P.
