Equilateral & isosceles triangles


Questions and Answers
  • 1. 

    What do you call a triangle whose sides are all equal?

    • A.

      Equilateral

    • B.

      Isosceles

    • C.

      Scalene

    Correct Answer
    A. Equilateral
    Explanation
    An equilateral triangle is a type of triangle where all three sides are equal in length. This means that each angle in an equilateral triangle is also equal, measuring 60 degrees. This is in contrast to an isosceles triangle, where only two sides are equal, and a scalene triangle, where all three sides are different lengths. Therefore, the correct answer to the question is "Equilateral."

    Correct Answer
    A. Two sides are equal
    Explanation
    An isosceles triangle is defined as a triangle with two sides that are equal in length. In an isosceles triangle, the third side can be of a different length, but at least two sides must be equal. Therefore, the correct answer is "two sides are equal."
