Answer:

B and E

Explanation:

An isosceles has two congruent (equal) angles and all of the angles add up to 180.

In option B, there are 2 congruent angles (70 and 70), and all the angles add up to 180 (70+70+40=180).

In option E there are 2 congruent angles (40 and 40), and all of the angles also add up to 180 (40+40+100=180).

The rest of the options do not fit the criteria for an isosceles triangle.
