The flashcards include the common formulas for the area and perimeter/circumference of various geometric figures (square, rectangle, triangle, parallelogram, trapezoid, circle) as well as for the surface area and volume of various solids (cube, cuboid, prism, cylinder, cone, pyramid, sphere). They also contain the trigonometric formulae for sine, cosine and tangent in a triangle as well as the Pythagorean theorem. Two file versions are included. One is designed so that the flashcards can be printed out immediately on both sides. The other is designed so that the flashcards can be printed out on one side and folded on top of each other.
