Pythagorean Theorem (Grade 12 NSC Matric Mathematics): Flashcards

$c^2 = a^2 + b^2$ where $c$ is hypotenuse

Longest side opposite the right angle

If $a^2 + b^2 = c^2$, triangle has right angle opposite $c$

Right-angled triangles only

Similar triangles

$AB^2 = BD imes BC$

$AC^2 = CB imes DC$

$MQ^2 = NQ imes PQ$

$MP^2 = QP imes NP$

Always longest side, opposite right angle
