What does center mean? Usually center means in the middle same distance from sides same distance from angles

Where is the center of a triangle?

Sketchpad

Don’t Forget move corners what kind of triangle? what happens when right triangle? – obtuse? – equilateral? which can be outside? which will never be outside?

Median: Segment from vertex to midpoint of opposite side Centroid: Where medians meet Altitude: Segment from vertex and is perpendicular to opposite side Orthocenter: Where altitudes meet Perpendicular Bisector: Segment perpendicular to a side and through its midpoint Circumcenter: Where perpendicular bisectors meet.

Which center is… Equidistant from angles? Circumcenter Equidistant from sides? Centroid
