Question

State whether given statements are true or false, if false justify
1)All Equilateral triangles are Isosceles.
2)All Isosceles triangles are Equliateral.
3)Right angled Trinagles can not be Isosceles.
4)Right angled triangles can be equliateral.

Answer 1

Answer:

1)All Equilateral triangles are Isosceles. - TRUE

2)All Isosceles triangles are Equliateral. - FALSE (because all sides of isosceles ∆s are not equal)

3)Right angled Trinagles can not be Isosceles. - FALSE ( because right angle ∆s can be isosceles with two sides equal in length)

4)Right angled triangles can be equliateral. - FALSE (because in equilateral ∆s all angles are of 60° not with 90°)
