What is the angle of 150?
On other pages there are instructions for constructing angles of 30°, 45°, 60° and 90°. By combining them you can construct other angles….Adding angles.

|---|---|
| 135° | 90° + 45° |
| 150° | 60° + 90° |
What are the steps to construct an angle?
Constructing an angle
- open the compass to the same dimensions as our original line.
- place the point of the compass on one end of the line and draw an arc.
- repeat this at the other end and the arcs should intersect where the tip of the triangle should be.
How do you draw a 120 degree angle with a protractor?
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°. Join F and G with the help of a ruler. We have ∠EFG = 120°.
How to construct an angle of 150 degrees using a compass?
To construct an angle of 150 deg using a compass, draw a line PQ (P, being on the left), say 12 cm long. Select the mid point of PQ as O. With O as center and a radius of 4 cm draw a semicircle cutting OP at R and OQ at S. With R as center and the same radius, 4 cm, cut the semicircle at T. Now, angle QOT is 120 deg and angle POT is 60 deg.
How do you make a 90 degree angle?
A 90-degree angle lies exactly halfway between a 120-degree angle and a 60 degree angle on a 360 degree scale. For its construction, you first construct a 60° angle and a 120° angle as discussed above. Then, construct an angle bisector between these two angles. Now, you get the required 90 degree angle. A 45 degree angle is the half of 90° angle.
What is a 120-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.
How do you add angles to a drawing?
On other pages there are instructions for constructing angles of 30°, 45°, 60° and 90°. By combining them you can construct other angles. Adding angles Angles can be effectively ‘added’ by constructing them so they share a side. This is shown in Constructing the sum of angles.
