It is the vertex
a midsegment of a triangle
the midsegment
circumcenter
A triangle has got 3 sides to it & that's why it's called a triangle. Three sides.
A triangle which has no two sides congruent is called a Scalene Triangle.
It is the vertex whose plural is vertices
a midsegment of a triangle
the midsegment
midsegment
circumcenter
The sides of a triangle do not meet in a point, so there is no "the common point".
The point where the perpendicular bisectors of the sides of a triangle intersect is called the circumcenter. This point is equidistant from all three vertices of the triangle and serves as the center of the circumcircle, which is the circle that passes through all the vertices of the triangle.
The point equidistant from the three sides of a triangle is the center of the triangle. The center of the triangle is the point of intersection of the medians of the triangle. The medians of a triangle are the line segments that join the vertices of the triangle to the midpoints of the opposite sides.
A triangle with three equal sides is called a equalateral triangle.
A triangle with no equal sides is called a Scalene Triangle.
A triangle with no equal sides is called a scalene triangle.
There is no such thing as a triangle with twelve sides.
