Figure B. equilateral triangle (small circle) inside of isosceles triangle (big cirlce)
Either you need each picture to represent a very small frequency which could require the reader to count up lots of images. Or the image represents a larger frequency and the user needs to be able to work out the fraction represented by partial images.
The hypotenuse is the longest side on a right triangle. It is the side that is opposite (directly across from and facing) the 90-degree angle. If your drawing shows a 90-degree angle by labeling it with a small corner (box), then the point of the corner always points toward the side that is the hypotenuse.
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
As small as you like. Infinitesimally small.

A Model. Money
Scientists create models to observe things they could no directly observed. A model can be used to represent things that happen at a very slow rate, a very high rate, or at a scale too small or too large to observe directly.
A general answer to your question would be: tools. For example, a microscope is a tool that makes it easier to understand things that are too small to observe directly. An x-ray machine is a tool that allows us to see inside of things that are too hard to see inside of directly. A knife is a tool that allows us to cut up large things to see what is inside of them.
Something that is so small that you cannot see it with the naked eye but must use a microscope to observe it
A seed symbolizes potential, growth, and new beginnings. It represents the idea of nurturing something small and watching it develop and flourish into something greater.
Magnifying glass
to observe tiny small things
We can observe small particles of iron and sulfur.
yeah...
your bell
A microscope.
