It is said that the triangle is as old as the dawn of time. Although the triangle tattoo looks very simple at the beginning, it actually has a lot of meanings behind the tattoo design. In western culture, triangle has many different meanings. Triangles have three sides, so they are often used to represent Christian and various scientific meanings.
Because triangles contain three sides and three angles, they are associated with the Trinity. Especially in Christianity, triangles can be used to represent the Holy Trinity, the father, the son and the Holy Spirit. For Christian believers, the tattoo can be used to express their dedication to these important gods, or as a symbol of their faith.
