Geometry Foldable

• Use this foldable to go with the Euler Points learned in Chapter 5– Circumcenter– Incenter– Centroid– Orthocenter

• Make your foldable using one sheet of legal size paper

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

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

Centroid – the balance point where the 3 medians of the triangle crossA median goes from the midpoint of one side to the vertex opposite

Orthocenter – where the 3 altitudes of the triangle crossAn altitude is measured perpendicular to a side and going to the vertex across

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
