Rolle's Theorem and its application in Tharu's traditional house

The indigenous people Tharu's have a distinctive culture and way of life. While performing daily tasks, they practice their own mathematical concepts and thinking. The study of mathematical ideas and skills that are common within a population but are often not included in the formal curriculum. This study intends to reveal the secret mathematical expertise and knowledge used in Tharu's traditional House. The observation and documentation analysis approach was utilized in this study's data collection to attain its objectives. This study is intended to uncover the mathematical concepts embedded in the construction of traditional Tharu houses. The resketching of the image of the traditional houses obtained in the field is carried out to facilitate the mathematical ideas in the construction of the traditional house. This finding demonstrates that Rolle's Theorem is applicable in practice and is clear enough to comprehend its principles from Tharu's traditional home.
