- Since any three points make up the corners of a triangle it is unsurprising, if somewhat unimaginative, to find a triangle among the constellations. Aratus and Eratosthenes knew this constellation as Δελτωτόν (Deltoton), because its shape resembled a capital delta (Δ), while Ptolemy in the Almagest listed it as Τρίγωνον (Trigonon), triangle.
In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
Matthew 5:16 NIV
