How do you construct a 105 degree angle without a protractor?

Expert Answer:

1. draw 120 degree angle.
2. then draw 90 degree angle.
3. the angle between the two rays will be 30 degree, draw the angle bisector.
4. now 90 + 15 = 105.

How do you construct an angle of 105 degree?

1: Draw a ray AB. 2: Considering A as the centre and width of any radius, draw an arc cutting AB at C. 3: Considering C as the centre and the same radius, draw an arc cutting the first arc at D. 4: Considering D as the centre and the same radius, draw another arc cutting again the first arc at G.

How do you construct an angle without a protractor?

Bisecting angles without a protractor

1. Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.
2. Place the compass on the point where one arc crosses an arm and draw an arc inside the angle.
3. Use a ruler to join the vertex to the point where the arcs intersect (D).

What kind of angle is 105 degrees?

obtuse angle-an angle between 90 and 180 degrees.

How do you make a protractor?

2 Method 2 of 3: Making a Pocket Protractor

1. Cut a sheet of paper into a square.
2. Fold the paper in half.
3. Fold the upper right corner into a triangle.
4. Fold the bottom right corner up to form a second triangle.
5. Fold the bottom left corner up.
6. Label the angles on your protractor.

What type of angle is 105 degrees?

Which all angles can be constructed by compass?

But we can use this method to construct some particular angles only such as 60°, 30°, 90°, 45°, etc. We can construct angles line 23°, 44°, 57°, etc., with accuracy using a compass and ruler.

Is 105 degrees an obtuse angle?

Obtuse angle- An angle that is greater than 90 degrees but lesser than 180 degrees is called an obtuse angle.
