The area formula of Leroy triangle is: s =1/2 [π-(31/2)] s 2. Leroy Triangle, also known as Leroy Triangle, Leroy Triangle and Arc Triangle, is a special triangle, which is a curved triangle with the vertex of a regular triangle as the center and the side length as the radius.

Triangle is a closed figure composed of three line segments on the same plane but not on the same straight line, which has applications in mathematics and architecture. Ordinary triangles are divided into ordinary triangles (three sides are unequal) and isosceles triangles (isosceles triangles with unequal waist and equal waist and bottom).

Leroy Triangle is a figure (curve) with constant width (equal): What is a figure with constant width? If you put a figure between two parallel lines and make it tangent to them, you can do this: no matter how the figure moves, as long as it is still on these two parallel lines, it will always be tangent to them, but the center point will form a circle.

Our family can often see sweeping robots using Leroy triangle, which makes use of the above principles.
