Triangle Incenter
Step 1: Using a straight edge or ruler, create triangle ABC
Step 2: Using your compass tool, create a circle with point A being the center ( don't change your compass)
Step 3: Where circle A intersects line AB name that F and where point A intersects line AC name that point G.
Step 4: Using your unchanged compass, and make a circle at point F and another at point G
Step 5: Where circle F and circle G intersect name that point k
Step 6: Using a straight edge or ruler, draw a line from point A to point K
Step 7: Repeat steps 2-6 on points B and C
Step 8: Where the 3 angle lines intersect, name that point M
Step 9: Using your compass tool, make a circle that fits exactly within the triangle, touching every side once, with the center being point M
