Construct a Circumcircle (circumcenter.....perpendicular bisectors
Why do they only do two?? The definition/theorem says intersection of 3????
Construct an Incircle (incenter....angle bisectors)
That last step is to help draw the circle.
It touches at a location perpendicular from the point to the side.
Median (needs midpoint)
Altitude (needs a perpendicular) think of that top point as a vertex
(onlinemathlearning video.... another video )
3 altitudes intersect (concurrency) and make an orthocenter (& therefor orthocircle)
Midsegment (needs 2 midpointx)
Do you know the definitions of these?
