Question

A triangle’s side lengths are whole numbers. If the measure of two of its sides are 1 cm and 13 cm, classify the triangle by its sides.
- isosceles
(explain in two sentences and in simple words)

Answer 1

The triangle cannot be formed with side lengths of 1 cm and 13 cm along with another whole number side because the third side must be less than the sum of the other two sides (14 cm) and greater than their difference (12 cm). Since there is no whole number that fits this range, the triangle is not possible, so we cannot classify it as isosceles or any other type.
