Questions & Answers

Q: How can a 120 degree angle be drawn using a 60 degree angle?

To draw a 120 degree angle, first draw a 60 degree angle. Then, using the same compass orientation, draw another arc to intersect the existing arc. Join the intersection point with the vertex of the angle, creating a 120 degree angle.

Q: What is the relationship between a 60 degree angle and a 120 degree angle?

A 120 degree angle is twice the measure of a 60 degree angle. By understanding this relationship, it becomes easier to construct a 120 degree angle using a compass.

Q: Can the same method be used to draw other angle measures?

Yes, using the concept of a 60 degree angle being half of a 120 degree angle, it is possible to draw various other angle measures by doubling or halving the angle measure.

Q: What resources does ExamFear.com provide?
