Which is the best definition of an isosceles triangle? A. A triangle that has three congruent sides B. A triangle in which no two sides are congruent C. A triangle that has at least two congruent sides

An isosceles triangle is a true geometric gem! It’s defined as a triangle that has at least two sides that are congruent, which, as you might guess, gives it that characteristic symmetry that's pleasing to the eye. The angles opposite those congruent sides are also equal, making it a popular choice in architecture and design for its aesthetic appeal. In real-world applications, isosceles triangles show up in various industries, from engineering designs to art and construction. For instance, the stability of an isosceles triangle is often utilized in bridge supports, where weight distribution plays a crucial role in safety and functionality. So next time you spot one, whether in a building or a piece of artwork, you can appreciate the science and artistry working hand in hand!
