Rechtwinklige Dreiecke Rechner
c2 = a2 + b2
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
If you know the length of the hypotenuse and one of the other two sides, you can use the Pythagorean theorem to find the length of the remaining side. For example, if you know the length of the hypotenuse is c and the length of one of the legs is a, you can find the length of the other leg by:
b2 = c2 - a2
Additionally, you can use the Pythagorean theorem to find the measure of the angles in a right triangle. You can use the inverse trigonometric functions such as arctan, arcsin, arccos to find the angles.
If you know the side lengths, you can use the trigonometric functions to find the angles:
sin α = a/c
cos α = b/c
tan α = a/b
It's important to note that the Pythagorean theorem holds true only for right triangles. If the triangle is not a right triangle, this theorem will not work.Die Rechner für rechtwinklige Dreiecke berechnen Winkel, Seiten (benachbart, gegenüberliegend, Hypotenuse) und Flächen eines rechtwinkligen Dreiecks und verwenden sie in der realen Welt. Zwei unabhängige Eigenschaften bestimmen vollständig jedes rechtwinklige Dreieck. Der Taschenrechner bietet eine schrittweise Erklärung für jede Berechnung.
Ein rechtwinkliges Dreieck ist eine Art Dreieck mit einem Winkel von C = 90°. In einem rechten Dreieck ist die Seite c, die dem Winkel C = 90° gegenüberliegt, die längste Seite des Dreiecks und wird als Hypotenuse bezeichnet. Die Variablen a, b sind die Längen der kürzeren Seiten, auch Beine oder Arme genannt. Variablen für Winkel sind A, B oder α (alpha) und β (beta). Die Variable h bezieht sich auf die Höhe des Dreiecks, dh die Länge vom Scheitelpunkt C bis zur Hypotenuse des Dreiecks.
Beispiele für die Berechnung des rechten Dreiecks:
- zwei Katheten a und b
- Kathete a und Hypotenuse c
- Kathete a und entgegengesetzten Winkel A
- Kathete a und benachbarten Winkel B
- Hypotenuse c und winkel A
- Hypotenuse c und höhe h
- fläche T und Hypotenuse c
- fläche T und Kathete a
- fläche T und winkel A
- Umkreisradius R und Kathete b
- Umfang p und Hypotenuse c
- Umfang p und Kathete a
- inradius r und Kathete a
- inradius r und fläche T
