Triangles

The app Triangles calculates all lengths and angles of the specified triangle depending on the following situations:1) Given the coordinates of the 3 points2) Given 3 line segments (s-s-s)3) Given 2 line segments and the angle in between (s-a-s)4) Given 2 line segments and the angle opposite to the longer one (a-s-S)5) Given 2 angles and the line segment between them(a-s-a)The cases 2) to 5) correspond to the sentences of congruence.The calculated triangle will be drawn in a 2d-coordinate-systemNumerous options show up in a menu that appears when you tap on a line segment.You may choose between the following objects:- Mid Perpendicular- Median- Bisectrix of angle- Height- Incircle- Circumcircle- Thales circle- Squares over sidesIf selected, the objects are shown in the graphic.
