Ella's geometry teacher asked each student to devise a problem and write out its solution. Here is Ella's work: A triangle has side lengths of 10, 11, and 15. What type of triangle is it? Procedure: 102 ?? 112 + 152 100 ?? 121 + 225 100 < 346 Conclusion: This triangle is an acute triangle. Which statement best summarizes Ella's work?

Confusing and incorrect. If the squares on the two shorter sides add to less than the square on the longer side, the triangle is obtuse.

Step-by-step explanation:. It would be a lot easier to understand if Ella uses standard notation for a number squared: carat ^2 if superscript is not available. Logic will help too. If you know that a^2 +b^2 = c^2 produces a Right Triangle, try to envision or sketch the lengths of a known acute triangle and see if the sum of the squares is greater or less than the square in the longest side.
