## Description

The app Triangles calculates all lengths and angles of the specified triangle depending on the following situations:<br>1) Given the coordinates of the 3 points<br>2) Given 3 line segments (s-s-s)<br>3) Given 2 line segments and the angle in between (s-a-s)<br>4) Given 2 line segments and the angle opposite to the longer one (a-s-S)<br>5) Given 2 angles and the line segment between them(a-s-a)<br><br>The cases 2) to 5) correspond to the sentences of congruence.<br><br>The calculated triangle will be drawn in a 2d-coordinate-system<br><br>Numerous options show up in a menu that appears when you tap on a line segment.<br>You may choose between the following objects:<br>- Mid Perpendicular<br>- Median<br>- Bisectrix of angle<br>- Height<br>- Incircle<br>- Circumcircle<br>- Thales circle<br>- Squares over sides<br>If selected, the objects are shown in the graphic.
