Answer:
I’m just going to address the first problem. You are asked to construct (draw) a triangle. I have to assume that you have a ruler, pencil and a protrator and that you know how to use them. If you follow the instructions, and draw the triangle, all of the questions should have obvious answers.
The questions can be answered without drawing the triangle, but that requires a higher level of abstraction. For example, since the triangle has two equal angles, it must be an isosceles triangle with two sides equal. That already answers a question. In addition, if a triangle has unequal angles, the side opposite a smaller angle will be smaller than the side opposite a larger angle.
I think the purpose of the question is to have you see these relationships for yourself, so the best approach is to follow the directions and draw the triangle.
