例句與造句

1. A reference triangle and its tangential triangle are in concurrent.
2. The circumcenter of the tangential triangle is on the reference triangle's Euler line,
3. Routine calculation shows that in every case these trilinears represent the incenter of the tangential triangle.
4. The circumcenter of the tangential triangle, and the center of similitude of the orthic and tangential triangles, are on the Euler line.
5. The circumcenter of the tangential triangle, and the center of similitude of the orthic and tangential triangles, are on the Euler line.
6. It's difficult to find tangential triangle in a sentence. 用tangential triangle造句挺難的
7. The tangent lines containing the sides of the tangential triangle are called the "'exsymmedians "'of the reference triangle.
8. A triangle's circumcircle, its nine-point circle, its polar circle, and the circumcircle of its tangential triangle are coaxal.
9. 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.
10. The tangential triangle is " A " B " C " ", whose sides are the tangents to the reference triangle's circumcircle at its vertices; it is homothetic to the orthic triangle.
11. While all triangles are tangential to some circle, a triangle is called the tangential triangle of a reference triangle if the tangencies of the tangential triangle with the circle are also the vertices of the reference triangle.
12. While all triangles are tangential to some circle, a triangle is called the tangential triangle of a reference triangle if the tangencies of the tangential triangle with the circle are also the vertices of the reference triangle.
13. The symmedian point of a triangle ABC can be constructed in the following way : let the tangent lines of the circumcircle of ABC through B and C meet at A', and analogously define B'and C'; then A'B'C'is the tangential triangle of ABC, and the lines AA', BB'and CC'intersect at the symmedian point of ABC . It can be shown that these three lines meet at a point using Brianchon's theorem.
