Question

poove that the a triangle
below have the
same area
class 9 maths​

Answer 1

Answer:

It's not necessary that two triangles with the same base have the same area…

But their altitudes should be the same as well, for triangle to be with equal area.

=> two triangles on the same base between the same parallel lines are equal in area.

Like.. area of tri 1 = 1/2 * base1 * altitude1

area of tri 2 = 1/2 * base 2 * altitude 2

In the above, if base1 = base 2

Altitude 1 = Altitiude 2

Then area( tri 1) = area (tri 2)
