Special right triangles and the Pythagorean Theorem can help solve many everyday problems. Here are a few examples:

1. Construction:

   • Workers use $45-45-90$ triangles to make sure buildings are straight and squared. This means both sides are equal in length, keeping everything balanced.

2. Design:

   • $30-60-90$ triangles help architects figure out heights and lengths when creating plans for buildings. This way, everything fits perfectly.

3. Navigation:

   • People can find distances by using triangular paths. For example, if you go $3$ miles north and then $4$ miles east, you can find that the direct distance is $5$ miles – like the sides of a $3-4-5$ triangle. This is super helpful for planning the best routes.
