Вопрос 13

Every side of a certain triangle measures 6 centimetres. What is the most exact name for this triangle?

  1. isosceles
  2. equilateralПравильный ответ
  3. scalene
  4. right-angled

Объяснение

All three sides are the same length, and the name kept for a triangle with three equal sides is equilateral. The weaker side name isosceles, which asks only for at least two matching sides, is also satisfied here, but the question calls for the most exact name and equilateral records more about the shape.
