True. While the triangle are not congruent, their sides are proportional to each other. This is usually accomplished via a <em>scale factor</em>. For example a triangle with the side lengths 3, 3, and 3, might be similar to a triangle with a scale factor of two, which will have side lengths of 6, 6, and 6.

Each individual question has a prob of 1/2 of being correct so its
(1/2)(1/2) .... (1/2) --- (8 times)
= (1/2)^8
= 1/256
so the answer is 1/256
