In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect at the triangle's centroid .
For 3 (non-collinear) points, if any angle of the triangle formed by those points is 120° or more, then the geometric median is the point at the vertex of that angle. If all the angles are less than 120°, the geometric median is the point inside the triangle which subtends an angle of 120° to each three pairs of triangle vertices. [10]
Median of a right angle of a triangle Thales' theorem states that if B C {\displaystyle BC} is the diameter of a circle and A {\displaystyle A} is any other point on the circle, then A B C {\displaystyle \triangle ABC} is a right triangle with a right angle at A . {\displaystyle A.}
In geometry, a cevian is a line segment which joins a vertex of a triangle to a point on the opposite side of the triangle. [1] [2] Medians and angle bisectors are special cases of cevians.
The parameters most commonly appearing in triangle inequalities are: the side lengths a, b, and c;; the semiperimeter s = (a + b + c) / 2 (half the perimeter p);; the angle measures A, B, and C of the angles of the vertices opposite the respective sides a, b, and c (with the vertices denoted with the same symbols as their angle measures);
Medina began his career illustrating such titles as Berserker and Megaton at Megaton Comics. He subsequently worked for First Publishing, on such titles as Dreadstar and Hammer Of God in the late 1980s, before starting to work for Marvel Comics on The Incredible Hulk, Warlock and the Infinity Watch, Blackwulf, Avengers, The Amazing Spider-Man, Marvel Knights Spider-Man and Venom: Dark Origin.
The angle formed by the symmedian and the angle bisector has the same measure as the angle between the median and the angle bisector, but it is on the other side of the angle bisector. The three symmedians meet at a triangle center called the Lemoine point. Ross Honsberger has called its existence "one of the crown jewels of modern geometry". [1]
The median of a normal distribution with mean μ and variance σ 2 is μ. In fact, for a normal distribution, mean = median = mode. The median of a uniform distribution in the interval [a, b] is (a + b) / 2, which is also the mean. The median of a Cauchy distribution with location parameter x 0 and scale parameter y is x 0, the location parameter.
