How do you prove that a quadrilateral is a rhombus because the diagonals
of the quadrilateral are perpendicular and bisect each other using the 2-column
proof method?

Collinear Points |
2003-01-13 |
|
From Gary:
Which of the 4 points are collinear when you construct the following concurrent lines or rays of a triangle? - P(1), the point where the angle bisectors intersect.
- P(2), the point where the altitudes (or extensions) intersect (inside or outside of the triangle).
- P(3), the point where the medians intersect.
- P(4), the point where the perpendicular bisectors (or extensions) of the three sides of a triangle intersect.
This is for my 9-12 high school class in geometry.
My name is Gary
Thanks for your help.
