Geometric Locus

Hello everybody! Here is some Geometric Locus review for anyone taking Geometry and prepping for their exams, or anyone that just loves math! I couldn't find any good videos on locus, but I included some helpful links. Enjoy~

Geometric Locus

Steps:
1. Draw a diagram showing the given information in the problem.  

2.  Read carefully to determine one of the needed conditions.  (Look for the possibility of the words "AND" or "AND ALSO" separating the conditions.)

3.  Plot the first locus condition.  If you do not see one of the locus theorems at work in the problem, locate one point that satisfies the needed condition and plot it on your diagram.  Then locate several additional points that satisfy the condition and plot them as well.  Plot enough points so that a pattern (a shape) is starting to appear, or until you remember the needed locus theorem for the problem. 

4.  Through these plotted points draw a dotted line to indicate the locus (or path) of the points.

5.  Repeat steps 2-4 for the second locus condition.

6.  Where the dotted lines intersect will be the points which satisfy both conditions.  These points of intersection will be the answer to the compound locus problem.
