What is 120 degree angle called?
What is 120 degree angle called?
obtuse angle
An obtuse angle can also be found out if we have the measure of the acute angle. In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°. Thus, it is an obtuse angle.
Can we draw 120 degree angle with compass?
Step 6: Now with the point of the compass at R, draw another arc to cut the arc drawn at step 5 at T. 3. Constructing a 120° Angle: 120° angle can be constructed using the logic that 60° + 120° = 180°.
What is value of sin 120 degree?
√3/2
Therefore, sin 120° = √3/2.
Is 120 degrees a straight angle?
120º angle This is an obtuse angle because 120 is a number greater than 90 and less than 180. So this angle measurement is between 90º and 180º: 90º < 120º < 180º.
How do you bisect an angle of 120 degrees?
Expert-verified answer question
- 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.
- m∠AOM = m∠BOM =
What quadrant does 120 degrees lie?
The angle 120∘ is in the second quadrant, and its related angle is 60∘.
How do you find sin 120 on the unit circle?
By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.
What is the bisector of 120?
Answer. Make a 60 degree angle and with the same radius make another semicerclefrom the 60 degree point to make it intersect with the line from where you want to draw the 120 angle (starting point) . The point gained when connected to the starting point will give 120 deree….
