Question

Prove that the triangle obtained by joining the midpoints of the sides of an isosceles triangle is also
isisoscele​

Answer 1

let the isosceles triangle be named as ABC where AB=BC and let D , E and F be the midpoints of sides AB, BC and CA respectively. now, F and E are midpoints => FE || AB and FE= 1/2 of AB. therefore triangle DEF is also isosceles.

Answer 2

Step-by-step explanation:

let the isosceles triangle be named as ABC where AB=BC and let D , E and F be the midpoints of sides AB, BC and CA respectively. now, F and E are midpoints => FE || AB and FE= 1/2 of AB. therefore triangle DEF is also isosceles
