Alapszöggel

Alapszöggel, also known as base angle, is a term used in geometry to describe the angles that are formed at the base of a triangle. In an isosceles triangle, the base angles are equal in measure. This property is a result of the triangle's symmetry, where the two sides that are equal in length (the legs) create congruent angles at the base. The sum of the base angles in an isosceles triangle is always 180 degrees minus the measure of the vertex angle. For example, if the vertex angle is 60 degrees, then each base angle would be (180 - 60) / 2 = 60 degrees. The concept of base angles is fundamental in understanding the properties of isosceles triangles and is often used in various geometric proofs and calculations.
