vertex angle
The angle formed by the legs of an isosceles triangle.
The vertex angle is the angle formed by the two sides of a polygon that intersect at the vertex or the point where the sides meet. In other words, it is the angle formed by the two adjacent lines that meet at a point in the middle of a polygon.
The vertex angle is usually measured in degrees, and its value depends on the type of polygon. For example, in an equilateral triangle, all angles are equal to 60 degrees, and thus, the vertex angle is 60 degrees. Similarly, in a square, all angles are equal to 90 degrees, and the vertex angle is also 90 degrees.
It is often essential to know the value of the vertex angle when calculating other properties of polygons, such as perimeter, area, and volume. Moreover, understanding the vertex angle concept is crucial in geometry problems, particularly those that deal with polygons.
