Draw a circle from the point F, using this measurement as the radius. Make sure the circle cuts both arms of the angle to form points of intersection. Choose the Compass tool to draw a circle using point Y as the centre. Unit 10.3: Mathematics 7: Focus on Understanding Bisect an Angle, Questions 4вЂ“5, Д«isect an Angle: Using GeometerвЂ™s Sketchpad XДў.

Leave the compass at the same setting and make an arc from point G, so that it intersects with the first arc. Mark an arc in the middle of the angle from point F. Set your compass to any distance greater than half way between points F and G. Make sure the arc cuts both arms of the angle to form points of intersection. Use the compass to draw an arc of a circle using point Y as the centre. Refer to: 01_segment_bisector.gspД«isect an Angle: Using a Compass 1.Draw an angle. Choose Line.Д¬A = 2.0 cm A student file for these instructions is available. The new line is the perpendicular bisector of the segment. The point of intersection is the midpoint of segment AD. Select the points and draw a line through them. CA = 2.0 cm To make a point of intersection:

Create the points of intersection for the two circles. Draw another circle, using the same measurement, with point D as the centre. To construct a circle from a point and a measurement: Select the point (F). Measure the distance from the new point on the circle to A. Make sure the circle cuts the segment more than half-way to point D. Choose the Compass tool to draw a circle using point A as the centre. Unit 10.3: Mathematics 7: Focus on Understanding Bisect a Line Segment, Questions 1вЂ“3, Д¬onstruct a Segment Bisector: Using GeometerвЂ™s Sketchpad 1. The line you draw is the perpendicular bisector of the segment AD. The line will bisect the segment, forming the midpoint. Use a straightedge to draw a line through the two points on the circles. It should intersect with the first circle at two points, above and below the segment.Д¤. Move to point D and draw a second circle. Make sure the circle cuts the segment more than half-way to point D.ДЈ. Use a compass to draw a circle using point A as the centre. Construct a Segment Bisector: Using a Compass 1.
