since this is a square, one of the angles must be 90
since this is a square, the two sides on either side of the 90 must be equal, implying that the other two angles in the triangle must be equal. since a+b+c = 180 in any triangle, the answer must be d: 45-45-90

The answer is d. because the sum of the angles must be 180 degrees and one of the angles (of a square) must be 90 degrees while tthe bisected angles (of a square) must be equal (45 degrees).

squares have right angles.
right angle = 90 degrees
two equal parts of right angle : 45, 45.
angles of triangle sums to 180
45-45-90

The answer to your first question is YES.
For the second question answer D. is the correct one. Remember that the angles of a triangle always add up to 180º.

It's d because the diagonals bisect the angles of the square, and their intersection is perpendicular.
