Lessons on Pythagorean

To which shape(s) does the Pythagorean theorem apply?

• All triangles
• Right triangles only
• Some right triangles and some isosceles triangles 
• Right triangles and circles.

The legs form what type of angle?

• Acute
• Obtuse
• Reflex
• Right

The longest side of a right triangle is called the...

• leg A
• leg B
• hypotenuse
• right angle

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

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

The Pythagorean theorem states that:

• The two smaller sides of a right triangle sum to equal the longest side.
• The squares of the two smaller sides of a right triangle sum to equal the square of the longest side.

If a² = 10 and b² = 30, what is c²?

• 20
• 40
• 300
• 90

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

The Pythagorean Theorem is
a² + b² + c²

• false
• true

solve for x

• 5552363959656.
• 10
• 100
• 89

What is the formula for finding the hypotenuse?

• a²⁺b²=c²
• a+b=c
• a-b=c
• c-a=c
