Mirror and water images, figure series, paper folding and counting triangles, with every figure computed so the answer is right by construction.

Mirror and water images

Mirror images of figuresA mirror held on the right swaps left and right only: top stays top, and every part lands the same distance behind the mirror line.
Water images of figuresA water image is a reflection in a horizontal line below the figure: top and bottom swap, left and right stay.

Figure series

Figure series: what comes next?Each figure changes the previous one by the same rule: an element turns by a fixed angle, moves a fixed number of places, or a count grows. Find the rule, apply it once more.

Paper folding

Paper folding and punchingUnfolding a crease adds the mirror image of every hole in that crease. Undo the folds from last to first; each fold doubles the number of holes.

Counting figures

Counting triangles in a figureCount systematically: by size, or by vertex. For lines fanning out from one vertex, any two lines and the base make a triangle: n(n − 1)/2.
