.-----------------A-------------------------------/\------------------------------/--\----------------------------/----\--------------------------/------\------------------------/--------\----------------------/_______\-------------------B-------------C-------The vertex of a triangle is:The point on a triangle or pyramid opposite to and farthest away from its base.So A is the vertex of this triangle.
A median of a triangle is a line from a vertex of the triangle to the midpoint of the side opposite that vertex.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.
Two
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
3 and they subtend from each vertex
1 triangle is formed.
Altitude: The altitude of a triangle is a perpendicular segment that connects a vertex and its opposite side. Let's construct the altitude of a triangle using a new triangle.
Always for it to be a complete triangle with three altitudes it would have to intersect at a vertex.
