It depends on what you mean by a centre. The most likely answer is a median.

A line of symmetry for a triangle is a line along which a triangle can be folded so that either side of the line is a mirror image shape of the other.An Isosceles triangle, with two equal sides, has a line of symmetry from the center of the base to its opposing vertex.An equilateral triangle with three equal sides has three lines of symmetry, each from the center of a side to its opposing vertex.Any other triangle type, called a scalene triangle, has no lines of symmetry,
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.
In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides.The center of the incircle is called the triangle's incenter.The center of the incircle can be found as the intersection of the three internal angle bisectors.You draw three lines. Each line from one triangle head point to the opposite triangle side and bisecting the angle. These three lines will intersect in one point which is the circle center.
The center of gravity of a triangle is its centroid. The centroid of a triangle is the intersection of the three medians.
Center of mass of an equilateral triangle is located at its geometric center (centroid).
