This puzzle does not have anything to do with the Master of Mystery geocaching global series, but conveniently just shares its name. This is a geocaching puzzle that even children should be able to solve! But first, we need to know about shapes...
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as colour, texture or material type. A geometric shape is the geometric information which remains when location, scale, orientation and reflection are removed from the description of a geometric object. That is, the result of moving a shape around, enlarging it, rotating it, or reflecting it in a mirror is the same shape as the original, and not a distinct shape.
Many two-dimensional geometric shapes can be defined by a set of points or vertices and lines connecting the points in a closed chain, as well as the resulting interior points. Such shapes are called polygons and include triangles, squares, and pentagons. Other shapes may be bounded by curves such as the circle or the ellipse/oval.

So there we go: Shapes.
Shapes are fundamental; delightful; and terrific. They are tremendous; honorific; yet wonderful. But aren't they just amazing!
Some Geocachers do not enjoy shape puzzles. But since we have all been educated about shapes, let us see if we can solve this puzzle together:
