Answer:
The first one is never true and the second one is sometimes true.
Step-by-step explanation:
The first one is never true because an equilateral triangle is a triangle that has all of the sides that are the same amount. An isosceles triangle is a triangle that has two sides that are the same value and one that has a different value from the two. So logically, this can never happen.
The second one is sometimes true because, like mentioned before, an isosceles triangle is a triangle that has two sides that are the same value and one that has a different value from the two. A right triangle is a triangle that has one angle in it that is a right angle. So this, can happen. One example of this is in the picture.
