plane figure
It is a plane figure, for example, a semicircle, a triangle, a kite.
A right angle triangle will fit into a semicircle.
Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).
All triangles inscribed in a semicircle with one side of the triangle being the diameter of the semicircle are right triangles.
Figures are not solid.
A semicircle
If all the angles are equal and acute, it will be an equilateral triangle.
A semicircle?
The only rectilinear figure is a triangle, or one composed of several triangles joined together.
The semicircle of Pythagoras refers to a geometric representation of the Pythagorean theorem, where a right triangle is inscribed in a semicircle. The diameter of the semicircle serves as the hypotenuse of the triangle, and the two other sides are the legs. According to the theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides, which holds true in this geometric configuration. This visual representation highlights the relationship between the triangle's dimensions and the properties of circles.
