What is a 120 angle?
< (less than) 90 degrees. 120. Obtuse. > (greater than) 90 degrees.
What is a 40 angle?
Acute Angle: An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles. In the adjoining figure, ∠X0Y represents an acute angle.
What type of angle is 45 degrees?
A 45-degree angle is an acute angle. It is half of the right angle or 90-degree angle.
What type of angle is 125 degrees?
Obtuse – any angle which measures more than 90 degrees but less than 180 degrees. These are “fat” angles that are very wide. Sample: angle DEF measures 125 degrees. Then angle DEF is obtuse.
How many 120 angles does it take to make a full turn?
There are 120 degrees in a third of a full turn. To determine this, you need to start with a full turn which is 360 degrees. If a full turn is 360 degrees, one-third of a full turn is 120 degrees since 360 divided by 3 is 120.
How do you turn your head 45 degrees?
Turn your head 45 degrees to the left (not as far as your left shoulder). Place a pillow under you so when you lie down, it rests between your shoulders rather than under your head. Quickly lie down on your back, with your head on the bed (still at the 45-degree angle).
How to make 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

How to draw an arc with a compass?
Now use compass and open it to any convenient radius. And with B as center , draw an arc which cuts line segment BC at Q . (as shown below) 3). Again use compass and opened to the same radius (as of step 2). And with Q as center , draw an arc which cuts first arc at R . (as shown below)
How do you make a 90° degree angle?
On the paper, draw a line segment longer than the ray of a the 90° 90 ° angle you need. Locate two points on the line segment at either end. Open the drawing compass to extend a bit beyond half the distance of the line segment (do this visually; no need for numbers). Swing an arc above and below the line segment.
