... The medians of ∆ABC are AM , CX , and BL . The centroid is point D. An altitude of a triangle is a segment that runs from one vertex perpendicular to the line that contains the opposite side. The orthocenter is the point of concurrency for the altitudes. An altitude may be inside or outside the tria ...

... because you get two options, acute or obtuse. Are the three angles all the same? If you move an intersection point the whole picture should move with it. Check the distances and angles. Did they change? Does the triangle still look the same to your Euclidean eyes? Now move one of the original two ve ...

EUCLIDEAN GEOMETRY 26 AUGUST 2013 Key Concepts
... Geometry is divided into Euclidean geometry and analytical geometry. Analytical geometry deals with space and shape using algebra and a coordinate system. Euclidean geometry deals with space and shape using theorems and a system of logical deductions, as developed by the Greek mathematician Euclid. ...
