In geometry, magnitude is the length of the hypotenuse of a right triangle.
In Euclidean geometry, 180. Other answers are possible, depending on the surface on which the triangle is drawn.
Not in traditional, 2 dimensional, euclidean geometry, because a triangles angles always equal 180º .However, there is a branch of Geometry that deals with a coordinate system on a sphere, instead of a plane, and in spherical geometry a triangle with three right angles is very much possible. Consider, for example, the triangle bounded by the Prime Meridian, 90o west longitude, and the equator.
The altitude of a triangle IS a geometric concept so it intersects geometry in its very existence.
The hypotenuse is the longest side of a right triangle. It is also the "c" value in the equation a-squared+b-squared=c-squared.The hypotenuse is the largest side of a right angle triangle.
