Forming and Bisecting Angles and Lines

Question 1

How do you bisect a line?

Answer 1

• draw a line AB
• put the compass at the center of point A and make two arcs at the top and bottom
• do the same with point B
• draw a line at the intersection of the arcs

Question 2

How do you divide a line into equal parts?

Answer 2

• draw a line AB
• at any convenient angle, draw line AC
• take the compass and mark off 10 equal divisions
• connect line BC
• use the set squares to make parallel lines at AB

Question 3

How do you bisect an angle?

Answer 3

• make a right angle
• put the compass at point A and make a semi circle through the angle naming it DE
• put the compass at point D and make an arc
• do the same with point E
• draw a line from point A to the intersections of the arc

Question 4

How do you construct a triangle?

Answer 4

• draw a line AB
• put the compass at point A and make an arc at the top
• do the same for point B
• join both points with the arcs
