Usage Examples English

  • A particularly elegant proof is due to François-Joseph Servois (1804) and independently Carl Friedrich Gauss (1810): Draw a line parallel to each side of the triangle through the opposite point, and form a new triangle from the intersections of these three lines.
  • The tangential triangle of a reference triangle (other than a right triangle) is the triangle whose sides are on the tangent lines to the reference triangle's circumcircle at its vertices.
  • In geometry, the tangential triangle of a reference triangle (other than a right triangle) is the triangle whose sides are on the tangent lines to the reference triangle's circumcircle at the reference triangle's vertices.
  • The triangle "AgBgCg" is called the Gossard triangle of triangle "ABC".

  • Let "DEF" be the triangle formed by the intersections of the adjacent angle trisectors of triangle "ABC".
  • The triangle "XYZ" is called the outer Napoleon triangle of the triangle "ABC". Napoleon's theorem asserts that this triangle is an equilateral triangle.
  • A right triangle is a triangle containing one right angle of 90°.
  • The medial triangle of a given triangle has vertices at the midpoints of the given triangle's sides, therefore its sides are the three midsegments of the given triangle.
