Triangle tangram puzzle

One big right-angled triangle, the same shape as five of the seven tans and twice as long on each side as a large one. It is one of the thirteen convex shapes a tangram can make. It is rated hard because three straight sides give almost nothing away. About three fifths of the pieces' edges are buried inside the figure, and the only corners to start from are the three points.

Drag the seven tangram pieces onto the shadow until the triangle is filled. Every shape here uses all seven, with no overlaps and nothing hanging over the edge. The pieces have exactly the silhouette's area, so covering the shadow is the whole win condition.
