- If all three sides of a triangle are congruent or of equal length, the triangle is classified as equilateral.
- If a triangle has different side lengths, that is, unequal side lengths, the triangle is classified as scalene.
- Also, where the length of two sides of a triangle are shown to be equal or congruent to each other, the triangle is classified as isosceles.
Therefore:
11. The triangle has two congruent sides, therefore, it is classified as isosceles.
12. The triangle has different side lengths, therefore it is scalene.
13. All the three sides of the triangle are congruent, therefore, it is an equilateral triangle.
