The positive curved three body problem is a natural extension of the planar Newtonian three body problem to the sphere \mathbbS2. In this paper we study the extensions of the Euler and Lagrange Relative equilibria (RE in short) on the plane to the sphere. The RE on \mathbbS2 are not isolated in general. They usually have one-dimensional continuation in the three-dimensional shape space. We show that there are two types of bifurcations. One is the bifurcations between Lagrange RE and Euler RE. Another one is between the different types of the shapes of Lagrange RE. We prove that bifurcations between equilateral and isosceles Lagrange RE exist for equal masses case, and that bifurcations between isosceles and scalene Lagrange RE exist for partial equal masses case.
