Centroid: The intersection of the medians in a triangle
Circumcenter: The intersection of the perpendicular bisectors in
a triangle
Orthocenter: Intersection of the altitutes of a triangle
Incenter: Intersection of the angle bisectors in a triangle
Incircle: A circle that is inscribed inside a triangle
Medialtriangle: A triangle formed by connecting the midpionts of each
segment of a triangle
Orthic
Triangle: a triangle formed by connecting
the intersections of the altitude with each side of the triangle
Center of Nine Point Circle:
The midpoint of the segment between the circumcenter and the orthocenter
Nine
Point Circle: A circle passing through
the midpoints of each segment of the triangle, the midpoints of
each segment from the orthocenter to the vertexes of the triangle
and the intersections of the altitudes with each side of the triangle.
Pedal
Triangle: Given any point inside the
triangle, it is formed from the points perpendular to the given
point and each side of the triangle
Centers of a
Triangle: Centers of a given triangle
(H,G,C, and I)
Euler Line: The line containing three centers of the triangle,
the orthocenter, incenter, and circumcenter
Isosceles triangle: Given the base and the altitude you can make an isosceles
triangle
Equilaterial
triangle: Given one side, a equilaterial
triangle is formed
Square: Given one side, a square is formed
Regular Pentagon: Given a side construct the pentagon
Regular Hexagon: Given a side constuct the hexagon
Regular Octagon:
Given a side construct the octagon
Golden Segment: A segement and its golden ratio
Trisected segment
