There are a few special facts about obtuse triangles that make them stand out from other triangles: The altitude drawn from the obtuse angle in an obtuse triangle lies outside the triangle.Īn obtuse triangle can never be a right triangle or an equilateral triangle. The sum of the other two angles in an obtuse triangle is always less than 90 degrees. The side opposite the obtuse angle is the longest side of the triangle. In an obtuse triangle, there is always one angle measuring greater than 90 degrees. Obtuse triangles have several interesting properties that distinguish them from other triangles:

An equilateral triangle has all sides equal and all angles measuring 60 degrees, making it an acute triangle. Obtuse-angled equilateral triangle: This triangle doesn’t exist. Obtuse-angled isosceles triangle: This triangle has two sides of equal length, and therefore, two angles are equal. As a result, all three angles are also different. Obtuse-angled scalene triangle: In this type of obtuse triangle, all three sides have different lengths. There are three main types of obtuse triangles, based on the length of their sides: We will also provide some solved examples and practice problems to help you enhance your understanding of this intriguing triangle. In this article, we will explore various aspects of obtuse triangles, including their types, properties, and formulas. The study of obtuse triangles can help students develop a deeper understanding of the principles of geometry and trigonometry. These triangles are unique and fascinating, as they possess special characteristics that distinguish them from other types of triangles, such as acute and right triangles.
