Triangle Inequality Theorem (Fill in the notes!!!)

• To form a triangle:

• The sum of any two sides of a triangle must be greater than the third side

Pythagorean Inequalities (Fill in the notes!!!)

• If the square of the longest side is greater than the sum of the squares of the two shorter sides, then the triangle is obtuse.

• If the square of the longest side is less than the sum of the squares of the two shorter sides, then the triangle is acute.

• If the square of the longest side is equal to the sum of the squares of the two shorter sides, then the triangle is right angled at 𝐵.
