+= Exercise Rep.03 -- Simple Drawing
+
+In this exercise you are going to work with the `Turtle` to draw a few simple shapes.
+
+Remember what a turtle can do:
+
+* Teleport to a specific location
+* Turn with a certain angle (left or right)
+* Move a certain distance drawing a line
+
+WARNING: We always want a _general_ solution which would also work with other input values. So try to _not_ assume (hard code) values except for those listed below, calculate the rest.
+
+== Eulerian Path
+
+An https://en.wikipedia.org/wiki/Eulerian_path[Eulerian path] is a finite graph which visits each edge exactly once.
+
+Put simply: you are going to draw a shape 'in one go' (= no 'lifting' of the pencil until done) while not drawing one line more than once.
+So you may visit nodes (points) multiple time, but _not_ the edges (lines).
+
+In German there is a little saying which is often taught to kids which, actually, is an Eulerian path: 'Das ist das Haus des Nikolaus' -- one line being drawn for each syllable.
+

+
+There are actually multiple possible paths which lead to a valid result.
+
+Your task is to use the `Turtle` to properly draw this shape.
+Use the following measurements and choose a good starting position:
+
+* normal length = `60`
+* short length = `42.2`
+* long length = `84.9`
+
+== Shapes
+
+Your next task is to draw some shapes:

+
+Make sure to select starting positions which do not let the shapes overlap.
+
+=== Octagon
+
+An https://en.wikipedia.org/wiki/Octagon[octagon] has, unsurprisingly, 8 corners.
+Use a side length of `40`.
+
+=== Rhombus
+
+A https://en.wikipedia.org/wiki/Rhombus[rhombus] has two pairs of equal angles and four sides of the same length.
+
+Use a side length of `60` and one of the angles has to be `82°`.
+
+=== Triangle
+
+The last shape actually consists of two triangles: one inner and one outer.
+
+image::pics/triangles.png[]
+
+* Both are isosceles triangles
+* The inner one has the following measurements:
+** short side = `6.0`
+** long side = `8.0`
+* Angles ares:
+** `48.19°`
+** `83.621°`
+* The _sides_ of the outer one are _offset_ by `1.5`
+* Could some code reuse be possible here 🤔
