Triangle Puzzle

How many triangles do you see?

Triangles are a fundamental geometric shape characterized by three sides, three angles, and three vertices. They can be classified into several categories based on their sides and angles, including equilateral, isosceles, and scalene triangles, as well as acute, obtuse, and right triangles. The sum of the interior angles of a triangle is always 180 degrees, making them essential in various fields like architecture, engineering, and computer graphics. Their structural properties provide stability, which is why triangles are commonly used in the design of bridges and buildings.
