Mark brainlist

Step-by-step explanation:

A triangle has three vertices. From each vertex, one median can be drawn.

Answer 2

Solution :-

• The vertex (plural: vertices) is a corner of the triangle. Every triangle has three vertices. The base of a triangle can be any one of the three sides, usually, the one was drawn at the bottom.

• A point where two line segments intersect is simply known as the vertex.

Example :-

As in the attachment, ΔPQR is a triangle and it is formed by three line segments.

1. The sides PQ and PR are intersected at point P. So, the point P is called as a vertex.
2. The sides PQ and QR are intersected at point Q. So, the point Q is called as a vertex.
3. The sides PR and QR are intersected at point R. So, the point is called as a vertex.
