An extra challenge

Triangle grids

Grids do not have to be made from squares.

Here is a grid made from triangles. The number 1 - 8 are missing from the grid. When a pair of numbers touch their total must be ODD.
Numbers do not touch at corners only on sides. Copy the grid and try to find where to put the numbers. There are several possible answers.
