If D, E and F are mid-points of sides AB, BC and CA respectively of an isosceles triangle ABC, prove that ∆DEF is also F, isosceles.
Solution:
Given: ABC is an isosceles triangle in which AB = AC
More Solutions:
- AC is its diagonal. Show that
- Show that the quadrilateral formed.

- The straight lines ED and EC.
- Prove that the line segment AD.
- AB || DC, E and F are mid-points of AD and BD.
- Prove that PQRS is a rhombus.
- G is mid-point of CD. Calculate:
- In a ∆ABC, AB = 3 cm, BC = 4 cm and CA = 5 cm.
- If P and Q are mid-points of the sides BC and CD.
