Pythagorean Basics

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.

When do we use the Pythagorean Theorem?

• To find a missing angle in a right triangle

• To find the missing length of a right triangle

• To find the area of a right triangle

• To find the slope of a right triangle

The Pythagorean Theorem is _________

• a + b = c

• a² + b² = c²

• a² + b² + c²

• A = LW

On your own paper, write an equation using the Pythagorean Theorem and solve for x.

• x = 15

• x = 7.9

• x = 21

• x = 225

Find the value of x.
