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

A triangle is scalene if all of its sides have different lengths. A triangle is isosceles if two sides have equal measurements with each other. A triangle is equilateral if all three sides have equal measurements with each other. That is how you will explain it to your classmate

Step-by-step explanation:

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.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
