The information about this figure would be used as a step in a proof of the Pythagorean theorem is AC² = AD² + CD²
Pythagoras theorem.
The theorem states that the square of the hypotenuse is equal to the sum of the square of the adjacent and opposite
From the given figure, the triangle ADC is right angles. Hence we can apply the theorem on the triangle.
- AC = hypotenuse
- AD = adjacent
- CD = opposite
According to the theorem:
AC² = AD² + CD²
Hence the information about this figure would be used as a step in a proof of the Pythagorean theorem is AC² = AD² + CD²
