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

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

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.

**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

- Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.
- Place the compass on the point where one arc crosses an arm and draw an arc inside the angle.
- 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

- Cut a sheet of paper into a square.
- Fold the paper in half.
- Fold the upper right corner into a triangle.
- Fold the bottom right corner up to form a second triangle.
- Fold the bottom left corner up.
- 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.
