+        In der beigefügten Abbildung sehen wir ein rechtwinkliges Dreieck, dessen drei Seiten die Längen a, b und c
+        besitzen. Auf jeder Seite ist ein Quadrat konstruiert. Das Quadrat auf der Seite a hat die Fläche a2, das
+        Quadrat auf der Seite b hat die Fläche b2 und das Quadrat auf der Seite c hat die Fläche c2. Der Satz des
+        Pythagoras besagt, dass die Summe der Flächen der beiden kleineren Quadrate gleich der Fläche des größten
+        Quadrats ist. Das bedeutet, dass a^2+b^2=c^2 (Satz des Pythagoras).

-    <h1>Satz des Pythagoras</h1>
-
-    <p>
-        Der Satz des Pythagoras wurde von dem griechischen Philosophen Pythagoras von Samos formuliert und im
-        dritten Jahrhundert vor Christus veröffentlicht.

-        In der beigefügten Abbildung sehen wir ein rechtwinkliges Dreieck, dessen drei Seiten die Längen a, b und c
-        besitzen. Auf jeder Seite ist ein Quadrat konstruiert. Das Quadrat auf der Seite a hat die Fläche a2, das
-        Quadrat auf der Seite b hat die Fläche b2 und das Quadrat auf der Seite c hat die Fläche c2. Der Satz des
-        Pythagoras besagt, dass die Summe der Flächen der beiden kleineren Quadrate gleich der Fläche des größten
-        Quadrats ist. Das bedeutet, dass a^2+b^2=c^2 (Satz des Pythagoras).
