QL-P8: Centroid QL-Diagonal Triangle
Coordinates:
1st CT-coordinate:
(l m + l n - m n)2 m n - 4 (l - m) (l - n) m2 n2 (note that this formula is independent of a,b,c)
1st DT-coordinate:
1
Properties:
- QL-P8 lies on these lines:
- The ratio of distances between QL-P9, QL-P8, QL-P11, QL-P10 in this order is 2 : 1 : 3.
- The ratio of distances between QL-P8, QL-P15, QL-P12, QL-P14, QL-P18 in this order is 2 : 1 : 1 : 2.
- d(QL-P8, QL-L9) = 2 * d(QL-P12, QL-L9) =4/3 * d(QL-P19, QL-L9)
