rovnoramenného

Rovnoramenného is a Slovak term that translates to "isosceles" in English, typically used in a geometric context. It refers to a triangle that has at least two sides of equal length. Consequently, the angles opposite these equal sides are also equal. This property is fundamental to the definition and study of isosceles triangles.

In an isosceles triangle, the side that is not necessarily equal to the other two is often called the base, and the angle opposite the base is known as the apex angle. The two angles adjacent to the base are called base angles, and they are always congruent. If all three sides of a triangle are equal, it is considered an equilateral triangle, which is a special case of an isosceles triangle where all angles are also equal (60 degrees each).

The concept of rovnoramenného extends beyond triangles. It can also describe other geometric figures, such as trapezoids. An isosceles trapezoid is a trapezoid where the non-parallel sides (legs) have equal length. In such a trapezoid, the base angles are also equal, meaning the angles at each base are congruent. This symmetry is a key characteristic of isosceles figures. The term emphasizes the presence of equality in specific dimensions or corresponding parts of a shape.
