Question 851043: So for homework i have been assigned "constructing triangles" on Khan Academy. The problem is: I cant understand it. It says a question like "Make a triangle with two 45 degree angles and one side length of 8" and then after spending a long time on making the triangle, i have to answer, "Are all triangles tat apply congruent?" I don't see any other triangles!!! I have to guess, and its a 50/50 chance to get it wrong! The present question says "How many triangles can we draw that have one angle measure equal to 45 degrees and one side of length 5?" Then the available answers are "None" "Only one" or "More than one." Please help me!
