IV. Two sides are equal in length. One way I remember this is in isosceles there are 2 e's and 1 l, an e is a side that is equal and the l is the other side. isosceles

III. and IV. as you need two sides to meet at 90° for it to be a right isosceles triangle, and two sides always need to be equal for it to be an isosceles. Otherwise it's scalene.
