Admin Which angle is 148 degree?
Explanation: A type of angle whose measurement is greater than 90° and less than 180° is called an Obtuse Angle. As we can see that, 148° is greater than 90° and less than 180° hence, it is an obtuse angle.
What is the type of angle 120 degree?
The angle measure ranges from 90° to 180°. 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.
How do you construct a 105 degree angle?
Expert Answer:
- draw 120 degree angle.
- then draw 90 degree angle.
- the angle between the two rays will be 30 degree, draw the angle bisector.
- now 90 + 15 = 105.
What is the name of 75 degree angle?
Answer: acute angle-an angle between 0 and 90 degrees.
How do you construct a 90 degree angle with a compass?
We can construct a 90º angle either by bisecting a straight angle or using the following steps.
- Step 1: Draw the arm PA.
- Step 2: Place the point of the compass at P and draw an arc that cuts the arm at Q.
- Step 3: Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R.
How do you make 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. Step 2: Take the compass and open it up to a convenient radius.
Which is the correct way to build an angle?
Depending on the inclination between the two arms, an angle may be acute (less than 90 degrees, say 60 degree angle), obtuse (more than 90 degrees) or right-angled (exactly 90 degrees). 60 degree is one of the most basic constructions, which facilitates constructing angles of several other measures. The steps are: Step 1: Draw a line segment.
How to make 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.
Which is halfway between a 60 and 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.
