What is a 120 angle?
< (less than) 90 degrees. 120. Obtuse. > (greater than) 90 degrees.
How do you construct a 120 degree and bisect it?
Answer
- Draw an angle of ∠AOB of 120°.
- Draw an arc from point O. This arc will cut the ray OA at any point C and ray OB at any point D.
- Draw two arcs of the same radii from the points C and D as centres.
- Join the point O to the point M by a ray OM. The ray OM will cut the angle ∠AOB into equal parts.
- m∠AOM = m∠BOM =
Is a 120 degree angle obtuse acute or right?
The different types of angles based on their measurements are: Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees. Obtuse Angle – An angle more than 90 degrees and less than 180 degrees.
How do you make a 120?
Constructing a 120° Angle: 120° angle can be constructed using the logic that 60° + 120° = 180°. Thus, we can understand that in order to construct 120° we can construct 60° angle and then further extend one of its arms as shown below in the figure.
How to construct an angle of 120° using compass?
Construct an angle of 120° using compass – Ex 11.1 Construct an angle of 120° using ruler and compass Steps of construction Draw a ray OA. Taking O as center and any radius, draw an arc cutting OA at B. 3. Now, taking B as center and with the same radius as before, draw an arc intersecting the previously drawn arc a
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 draw an arc with a compass?
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.
How to construct an angle of 120° using ruler?
Construct an angle of 120° using ruler and compass Steps of construction Draw a ray OA. Taking O as center and any radius, draw an arc cutting OA at B. 3. Now, taking B as center and with the same radius as before, draw an arc intersecting the previously drawn arc at point C. 4.
