# The median of a triangle divides it into two

a. triangles of equal area

b. congruent triangles

c. right triangles

d. isosceles triangles

**Solution:**

Consider a triangle ABC

Construct AP perpendicular to BC

As D is the midpoint of BC

BD = DC

Let us multiply both sides by AP

BD × AP = DC × AP

Here

1/2 × BD × AP = 1/2 × DC × AP

ar (Δ ABD) = ar (Δ ACD)

Median of a triangle divides it into two triangles of equal area.

Therefore, the median divides it into two triangles of equal area.
