The longest side of a right triangle is DIRECTLY ACROSS from the...

• right angle.
• acute angle.
• obtuse angle.

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

Find the length of the missing side. 

• 17 cm
• 22 cm
• 15 cm
• 13 cm

Find the length of the missing side. 

• 20 in.
• 68 in.
• 16 in.
• 80 in.

What is the final step in solving this work for c?
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²

• Divide both sides by 2

• Take the square root of both sides

• 25 IS the final answer
