Sure! Here's a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
In this game, the player needs to identify a valid combination of angle, angle, and side congruence by matching them with pictograms. To play the game, the player simply needs to click on the "Start Game" button, which will generate a random combination of pictograms representing angle, angle, and side. The player then needs to figure out if they form a valid combination according to the angle angle side congruence theorem.
Please note that this is a basic implementation and can be expanded further to include additional game mechanics, scoring, and user interactions as desired.
