Step-by-step explanation:
both statements are wrong.
a right (or right-angled) triangle has a 90° angle. that is all.
an equilateral triangle has 3 equally long sides.
but that also implies that the 3 angles must be equal too.
the sum of all angles in a triangle must be 180°.
if all angles are equally large, that means
180 = 3×angle
angle = 180/3 = 60°.
that means none of the angles can be 90°, so, no right-angled triangle can be equilateral.
and no equilateral triangle can be right-angled.
