- a2 + b2 = 102 + 242 = 100 + 576 = 676
- c2 = 262 = 676
- 82 + 152 = 64 + 225 = 289,
- but 162 = 256
Example: Does this triangle have a Right Angle?
Does a2 + b2 = c2 ?
They are equal, so ...
Yes, it does have a Right Angle!
Example: Does an 8, 15, 16 triangle have a Right Angle?
Does 82 + 152 = 162 ?
So, NO, it does not have a Right Angle

The longest side of the triangle is called the "hypotenuse", so the formal definition is:
-
Example: Does this triangle have a Right Angle?
Does a2 + b2 = c2 ?
Does (√3)2 + (√5)2 = (√8)2 ?Does 3 + 5 = 8 ?Yes, it does!
So this is a right-angled triangle

The longest side of the triangle is called the "hypotenuse", so the formal definition is:
In a right angled triangle:
the square of the hypotenuse is equal to
the sum of the squares of the other two sides
