Make your foldable using one sheet of legal size paper

3. Circumcenter – where the 3 perpendicular bisectors cross
Is the center of a circle that goes around the outside of a triangle and touches only the vertices

5. Incenter – where the 3 angle bisectors cross
Is the center of a circle that goes inside a triangle and touches the sides of the triangle at only one point

7. Centroid – the balance point where the 3 medians of the triangle cross
A median goes from the midpoint of one side to the vertex opposite

9. Orthocenter – where the 3 altitudes of the triangle cross
An altitude is measured perpendicular to a side and going to the vertex across

10. For a right triangle the circumcenter is always on the hypotenuse and the orthocenter is always at the 90º angle.
For all triangles the incenter and centroid are always inside the triangle
