Pythagoras' Theorum Summary - Maths

Pythagoras' Theorem - Summary

• The triangle must be a right angled triangle.
• The longest side is the hypotenuse, we label that C.
• It doesn't matter which way round we label A and B.
• The equation: C² = A² + B². If we need to find A or B, we must rearrange the equation.
• For 3D Pythagoras, we must try and split the shapes down into right angled triangles.
• Some questions may involve us using Pythagoras even though the question doesn't always ask for it so watch out!
• Always remember once you have squared the numbers and added/subtracted them, you must square root and round to the asked amount of significant figure or decimal place when asked.
