Triangle ABC has three angles, x, y and z.

Is ABC isosceles?

1) (x+y) - (x+z) = 0

2) (y+z) - (y+x) = 0

Is ABC isosceles?

1) (x+y) - (x+z) = 0

2) (y+z) - (y+x) = 0

FORM ONE

Y-Z = O IE Y=Z ANGLES CAN NEVER BE ZERO ....SUFF

FROM TWO

Z =X ......SUFF

MY ANSWER IS D

D

Statement 1:

x(y-z) = 0

x cannot be 0. So, y=z. SUFF

Statement 2:

y(z-x) = 0

y cannot be 0. So, z=x. SUFF

isosceles = two angles or two sides are equal.

1) (x+y) - (x+z) = 0

2) (y+z) - (y+x) = 0

1) x+y-x-z=0 , y = z , so angles y and z are equal. yes.

2) y+z-y-x=0, z=x, so angles z and x are euqal. yes.

D, EACH is SUFF.

Why can it not be equilateral and therefore C?

If y=z, we do not know x?

Since the question is "Is ABC isosceles?", we do not need to worry whether it is equilateral or not.
