Advanced Topics

The Pythagorean Theorem

Right Triangles Unlocked

The Pythagorean Theorem connects the sides of a right triangle. If a triangle has a right angle (90°), then:

\[ a^2 + b^2 = c^2 \] Where \( a \) and \( b \) are the legs and \( c \) is the hypotenuse.

How to Use It

  • Plug in the lengths you know.
  • Solve for the missing side.

Real-Life Examples

Builders use it to find the length of ladders, or to check if corners are square.

Fun Fact

This theorem works only on right triangles!

Key Formula

\[a^2 + b^2 = c^2\]

Examples

  • If legs are 3 and 4, hypotenuse is 5.

  • A ramp with height 6 ft and base 8 ft has length 10 ft.

In a Nutshell

The Pythagorean Theorem finds missing sides of right triangles.
