  1. Loci 1.) Draw the locus of points always 4cm away from a point A. 2.) Draw a line 4cm long. Find the locus of a point always 3cm away. 3.) Draw a triangle. Draw the locus of this shape 2cm away. 4.) A light can shine up to 5.5m away draw the region the light shines. 1m = 1cm. 5.) Two points are 6cm apart, draw the locus of points equidistant from both points. 6.) Two lights A and B are 3m apart if both lights can shine up to 2m away Draw the diagram and shade the region that both lights cover. Use 1cm = 1m. 7.) Two dogs are tied up, 5m apart. If the 1st dog has a leash of 3m and the 2nd a leash of 2.5m. Draw and shade the region where both dogs can be. Use 1cm = 1m. 8.) A building 6m by 5m is to have a fence that is always 2m away from the building. Draw the locus of points always 2m from the building. Use 1m = 1cm.

  4. LOCI A locus is a set of points that obey a given rule. (1.) The locus of points a constant distance from a fixed point. P

  5. (2.) The locus of points a constant distance from a line.

  6. (3.) The Locus of points equidistant from 2 points: (Perpendicular Bisector) A B

  7. (4.) The Locus of points equidistant from two lines. B A C
