Our math textbook does not require the portion "angled" in the name of isosceles right triangles nor scalene right triangle. Please consider allowing these variations. In a math classroom they would be considered correct answers.

Although 'angled' appears in the answer box (the UK answer), the American 'isosceles right triangle' and 'scalene right triangle' have always been valid type-ins.
