Answer: See Explanation below.
For part A, the right isosceles triangle, you must have a triangle with a right angle, 90 degree. Then, the two legs must be congruent.
For part D, draw a triangle with all 3 angles being 60. This will make the sides congruent also.
For part C, the three measures of your triangle will be 57, 82 and 41. The measures of the sides don't matter, they will all be different.
