Pythagoras theorem: hypotenuse² = opposite² + adjacent²
Step-by-step explanation:
To know if a triangle is a right angle, we need to have the length of each sides of the triangle. Then we would apply Pythagoras theorem to determine if it is truly a right angled triangle.
Pythagoras theorem is a theorem in the form of an equation which shows the relationship between the sides of a right angled triangle.
let the sides of the right angled triangle be:
opposite =a, adjacent = b and hypotenuse = c
Using Pythagoras theorem
hypotenuse² = opposite² + adjacent²
c² = a² + b²
If the left hand side of the equation = the right hand side of the equation, it is a right angled triangle.
