Acute and obtuse triangles - Wikipedia
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
Acute Triangle - Properties, Formulas, Examples - Cuemath
An acute triangle is a triangle in which all the three interior angles are less than 90º. Although the three interior angles of the acute triangle lie within 0° to 90°, their sum is always 180 degrees. Learn how to find the area and perimeter of an acute triangle with the help of solved examples.

What is Acute Triangle? - Definition Facts & Example - SplashLearn
An acute triangle is a type of triangle in which all the three internal angles of the triangle are acute. Acute triangles are also called acute-angled triangles. Even though the length of the sides of acute triangles differs, the interior angles are never more than 90°.
Acute Triangle – Definition with Examples - Brighterly
In this article, we’ll cover the acute triangle definition, the different types of acute triangles and their properties, and share examples of acute triangles and practice math problems.
Triangle Calculator
Any triangle that is not a right triangle is classified as an oblique triangle and can either be obtuse or acute. In an obtuse triangle, one of the angles of the triangle is greater than 90°, while in an acute triangle, all of the angles are less than 90°, as shown below.
Acute triangle - Math.net
An acute triangle is a 3-sided polygon in which the interior angles (the angles formed inside the triangle) all measure less than 90°. An example of an acute triangle in real life is a yield sign:
Acute Triangle -- from Wolfram MathWorld
A triangle in which all three angles are acute angles. A triangle which is neither acute nor a right triangle (i.e., it has an obtuse angle) is called an obtuse triangle.
Right Triangles, Acute Triangles and Obtuse Triangles
In these lessons, we will learn how to classify triangles by their angles: Right Triangles, Acute Triangles, Obtuse Triangles. We can also classify triangles by the lengths of their sides: Equilateral Triangles, Isosceles Triangles, Scalene Triangles.
