Question

Determine if 7, 8, and 13 can be the lengths of the sides of a triangle. If yes, classify the triangle

Answer 1

You can use the Pythagorean Theorem to figure this out.

The 2 shorter legs squared will equal the longest side (Hypotenuse)

A^2 + b^ 2 = C^2

So 7^2 + 8^2 = 13^2

Is this true? If so, then your answer is yes.

Answer 2

As for classifying the triangle, I am unsure.

Answer 3

3 unequal lengths , 7, 8, 13 = scalene triangle

other classifications
2 equal lengths = isosceles
1 angle more than 90° = obtuse
1 90° angle = right angle
3 equal sides/ 3 equal angles = equilateral
