Question

Define altitude and median. name triangle in which altitude and median is same

Answer 1

Altitude : Altitude of a triangle is the shortest distance form a vertex to its opposite side.

Median: Median is the straight line that joins a vertex of a triangle with the mid point of the opposite side to that vertex.
In equilateral triangle all medians and altitudes are same.

Answer 2

$\huge \underline \bold { \pink{A} \red{l} \blue{t} \green{i} \purple{t}{u} \orange{d} \red{e}} :-$

It is a line segment from a vertex perpendicular to the opposite side.

$\huge\underline \bold{ \red{M} \green{e} \pink{d} \blue{i} \purple{a} \orange{n}} : -$

It is a line segment joining a vertex to the midpoint of opposite side, bisecting that side.

In equilateral triangle altitude and median are same.
