If D, E, F are midpoints of the side BC, CA, AB of a triangle ABC then AD, BE, CF are called _______ of triangle ABC

$\huge{\tt{\colorbox{aqua}{AnswEr:}}}$

Triangle ABC is an equilateral triangle.

⇒ AB = BC = AC

DE = 1/2 AB

EF = 1/2 BC

⇒ EF = 1/2 AB [Since AB = BC = AC]

DF = 1/2 AC

⇒ DF = 1/2 AB [Since AB = BC = AC]

DE = EF = DF

∴ ΔDEF is an equilateral triangle.

so Answer is Equilateral triangle ✔️✔️✔️

Answer 2

median. ( a line from a vertex to the midpoint of opposite side)
