Final answer:
Similar triangles and polygons are seen in architecture for stability, in triangulation for navigation and surveying, and in art for composition framing.
Step-by-step explanation:
Examples of similar triangles and polygons in the real world are numerous and can be found in various fields. Thinking of a triangle, we know it's a three-sided figure on a plane, with angles summing to 180 degrees. Real-world examples include:
- Architectural structures, where triangular bracing provides stability.
- The method of triangulation is commonplace in navigation and surveying.
- Certain artistic compositions, where triangles are used to frame subjects.
These triangles and polygons often share similar angles and proportionate sides, illustrating a direct application of geometric principles in everyday life.
