  3. Right. Since there are 180 degrees in a triangle, this must be an equilateral.

  4. Sum of angle in triangle=180°

    180°=60°+60°+third angle

    180°=120°+third angle

    third angle=180°-120°=60°

    Equilateral triangle has three angles equal 60°

    You triangle is equilateral triangle.
