IMO C

1) and 2) are insufficient alone.
Both we have r° = s° ==> the triangle is an equilateral one.

When r=s; can you explain how this triangle becomes an equilateral one ?

in the figure, I can see s°, s° and r° as the angles of the triangle.
if s°=r° we have all three angle of the triangle that rare equals. so s=r=180/3=60.

an equilateral triangle is one that has 60° for each angle.

My bad , I misread r as y and was confused all this while. Thanks !
