Definition

An obtuse triangle is a triangle with one angle greater than 90 degrees.

Description

An obtuse triangle is characterized by having one of its interior angles greater than 90 degrees. This type of triangle is significant in geometry as it represents a unique class of triangles with specific properties.

In real-world applications, obtuse triangles are used in various design and architectural projects where specific angle measurements are required. For example, understanding the properties of obtuse triangles helps in creating structures with unique shapes and angles.

In math education, learning about obtuse triangles helps students understand the broader concepts of triangle classification and the relationships between angles and side lengths. It also provides a foundation for more advanced topics, such as trigonometry and calculus. By mastering this concept, students can apply their knowledge to solve practical problems and develop a deeper understanding of geometric principles.
