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
