Answer:
Answer choices D and E
Step-by-step explanation:
If a triangle has two 45 degree angles, then the third angle must be 180-45-45=90 degrees, since the total interior angles of a triangle add up to 180 degrees. A triangle with a 90 degree angle is called a right triangle, or answer choice D. Also, since the triangle has two angles that are identical, it is an isosceles triangle, or answer choice E. Hope this helps!
