Congruent triangles can be seen in the construction of buildings, road signs, and art.
One real-life example of congruent triangles is in the construction of buildings. When constructing a roof, for example, the triangular trusses used are often congruent to ensure stability and balance.
Another example can be found in road signs. Many road signs are designed as equilateral triangles, which means that all three sides are congruent.
Lastly, congruent triangles can be seen in the field of art. Tessellations, such as those found in Islamic architecture or the artwork of M.C. Escher, often use congruent triangles to create visually appealing patterns.
