Question 10

Determine if the values 3, 5, and 7 represent the side lengths of a right triangle, an obtuse triangle, or an acute triangle. Justify your answer.

Revolt · Accepted Answer

Responses may vary but should include some or all of the following information: Since 3 + 5 > 7, the side lengths can form a valid triangle. Comparing the sum of the squares of the shorter side lengths to the square of the longest side length, we get that 3^2 + 5^2 = 34 and 7^2 = 49. Since 34 < 49, the triangle is obtuse by the obtuse triangle inequality theorem.
