What is the angle of 125 degree?
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 do you construct a 125 degree angle with a protractor?
We draw a line segment PQ of some length using a ruler. Then with point Q as the focus we measure an angle of 125° with a protractor and mark it on the figure, then we join the line segment from B to the mark and name the point R. Thus the angle ∠PQR = 125° is obtained.
How do you draw a 127 degree angle with a compass?
Following steps:
- Draw a line using scale.
- as a center draw an angle using protector like.
- as a center draw an arc using compass which cuts line and at.
- From point , draw an arc with any measure.
- By same measure from point , draw an arc which cuts before arc at.
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 =
What type of angle is 127 degrees?
obtuse angle-an angle between 90 and 180 degrees.
What are the angles you can make with a compass?
Angles that can be constructed by Compass and Straightedge are 15,30,45,60,90,120,150,180 degrees and some other angles can be constructed by Bisection (for eg.
How to make a 20 degree angle using ruler?
Constructing a 20 Degree Angle using Ruler and Compass 1 Step 1:. 2 Step 2:. This will be your normal 60 Degree angle arc. 3 Step 3:. Till Step 3, it was a normal construction. Step 4 is where the ‘Twist’ occurs!!! 4 Step 4:. Angle JAB is your 20 degree angle! Now you can easily construct angles measuring… More
How do you make an angle of 60º?
Construction of an Angle of 60º Step 1: Draw any ray AB. Step 2: Taking A as the centre and with any suitable radius, draw an arc PQ that cuts AB at Q. Step 3: Taking Q as the centre and radius equal to AQ, draw an arc cutting the previous arc PQ at R. Step 4: Join AR and produce it to get AC. Step 5: ∠BAC is the required angle equal to 60º.
How to draw an equilateral triangle step by step?
⇒ ΔOPR is an equilateral triangle. Step I: Draw ∠AOB = 60º by using the steps mentioned above. Step II: With centre O and any convenient radius draw an arc cutting OA and OB at P and Q respectively. Step III: With centre P and radius more than (PQ), draw an arc in the interior of ∠AOB. Step VI: The angle ∠AOC is the angle of measure 30º.
