Similar Triangles Real Life Applications

Front

What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Example of using similar triangles in architecture:

Back

To find the height of a building, a surveyor can measure the length of its shadow and the length of a smaller object’s shadow, using the ratio of their heights.
