Ikat weaving has long existed as among the customs and traditions of the ancient people known as T'boli in Lake Sebu, South Cotabato. It still exists and utilizes the rich natural and vast resources of the land of Dreamweaver who are considered as the major indigenous people in the island of Mindanao. T'nalak, as they call this ikat weaving, also exists in some parts of South East Asian countries. This study combines descriptive and non-parametric statistics in determining the presence of mathematics in one of their finest works, the hand-woven T'nalak, known as Bed Henda, and one of fifty (50) designs of T'nalak. The coded images formed using the phylogenetic motif and computerized image process in analyzing the Bed Henda geometric patterns have almost the same shape. Its inner shape there is a diamond or oblong type, while, its outer shape is hexagonal or an elongated irregular shape.
