Practice and Revision - Pythagoras Theorem
Let us practise and revise what we learned about pythagoras theorem. The Pythagoras theorem states that in a right triangle, the square of t
Core concept
The Pythagoras theorem is stated as a²+b²=c², where c is the hypotenuse (longest side) and a, b are the other two sides of a right triangle.
How it works
This theorem only applies to right triangles, where one angle measures exactly 90°, and c is always opposite this right angle.
Why it matters
The converse of the Pythagoras theorem states that if a²+b²=c² for a triangle's sides, then the triangle must be a right triangle.
Key detail
The Pythagoras theorem has practical applications in construction, navigation, and calculating distances that cannot be measured directly.
