Carmelo Ellul Construct an Angle of 60° A powerpoint presentation by Carmelo Ellul Head of Department (Mathematics)

Construct an Angle of 60° Task: Using ruler and compasses construct an angle of 60°. Task: Conclusion: Construction: Draw a straight line of any length and on it mark a point X. ZXY is the required angle. Label the point of intersection of the two arcs Z. Centre X, any radius, draw an arc to cut the line at Y. Join XZ. Centre Y, same radius, draw another arc. Z X Y
