Question

how do you construct the orthocenter of an obtuse triangle?

Answer 1

ortho means 90 degrees; im assuming that is the 90s that go from the midpts of the sides?

Answer 2

altitudes; not midpts .. soo colose

Answer 3

maybe? its been awhile

Answer 4

It's the point where the three altitudes of a triangle intersect.

Answer 10

Oh - I see :-)

Answer 11

there is a little applet on this page that will let you see how the orthocentre changes as you change the shape of the triangle: http://www.mathopenref.com/triangleorthocenter.html

Answer 12
