2, 2, 2
4, 5, 6
2, 2, 4
12, 12, 14

Answer 1

in the explanation

Explanation:

Which of the following side measurements could make an equilateral triangle and isosceles triangle?

2, 2, 2

4, 5, 6

2, 2, 4

12, 12, 14

1. The sides of an equilateral triangle are congruent, which means that all sides are of equal length. All the interior angles are equal(60 degrees) too.
2. A triangle with two equal sides. The angles opposite the equal sides are also equal. Isosceles Triangle. Two equal sides and two equal angles.

2,2,2 = 3 congruent sides = equilateral

4,5,6 = 3 different sides not equilateral not isosceles

2,2,4 = 2 congruent sides = isosceles

12,12,14 = 2 congruent sides = isosceles
