Locus a fixed distance from a point
Locus a fixed distance from a point.
- A locus is the set of all points satisfying a distance rule.
- Distance to a straight line is always measured perpendicularly.
- For two conditions, keep only the region satisfying both.
Example 1
Draw the locus of points exactly 3 cm from P.
Every point on the circumference is the same distance from P. The interior is not included when the distance is exactly specified.
Example 2
Draw the locus of points exactly 4 cm from P.
Every point on the circumference is the same distance from P. The interior is not included when the distance is exactly specified.
Your turn
Draw the locus of points exactly 5 cm from P.
Check answer
Every point on the circumference is the same distance from P. The interior is not included when the distance is exactly specified.
Draw the locus of points exactly 6 cm from P.
Check answer
