Question

In triangle ABC, the perimeter is 16 cm. find the perimeter of the triangle obtained by joining the mid-points of sides triangle abc​

Answer 1

Answer:

Step-by-step explanation:

Answer:

36 cm

Step-by-step explanation:

Perimeter of triangle ABC = 72 cm

D,E and F as teh mid-points of the sides of the given triangle.

So, by mid point theorem

DE=1/2AC

FE =1/2AB

DF=1/2BC

So, Perimeter of triangle DEF = DE+EF+DF =  

Hence the perimeter of the triangle DEF is 36 cm
