In an isosceles trapezoid, one of the angles is 45 degrees. Find the rest

Since the trapezoid is isosceles, then its angles at the bases are equal to each other, therefore, the second acute angle is also 45.

Since the trapezoid has the sum of the angles at the lateral side equal to 180, the obtuse angles of the trapezoid will be equal: 180 – 45 = 135.

Answer: The angles of the trapezoid are 45 and 135.
