Question

Your classmate is unsure about how to use side lengths to determine the type of triangle. How would you explain this to your classnate?

Answer 1

Sample Response: First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.

Answer 2

Explanation:

If all three sides have the same length then it's an equilateral triangle, if two sides are congruent then it's an isosceles triangle, and if there are no sides that have the same length then it's a scalene triangle.
