Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. The types of triangles classified by their sides are the following:

Example 1: Classify the triangle by its angle measures. If we examine the angle measures closely, we can see that the triangle is composed of two angles that measure less than [latex]90^\circ[/latex] (acute angles) and one that is more than [latex]90^\circ[/latex] (obtuse angle).
The classifying triangles calculator can help you name a chosen triangle. Triangles have two types of names. With our calculator, you'll learn how to classify triangles by their sides. Then, you'll also find out how to name them based on the sizes of their angles.
Mar 29, 2019 · Classify the triangle according to the measurement and the type of angles. Name the triangle as an obtuse triangle if any of the angles are greater than 90 degrees. An obtuse triangle will only have 1 obtuse angle. Classify the triangle as a right triangle if the triangle possess a right angle of 90 degrees.
What are the 3 Triangles Classified Based on their Angles? On the basis of angles, triangles are classified into acute triangle, right triangle, and obtuse triangle. Acute triangle: In an acute triangle, all the angles measure less than 90°. Right Triangle: When one angle of a triangle measures 90°, it is called a right-angled triangle.
Oct 26, 2023 · Step-by-step Guide: Classifying Triangles. Based on Sides: Equilateral Triangle: All three sides are of equal length.All three angles measure \(60^\circ\). Isosceles Triangle: Two sides are of equal length.The angles opposite these equal sides are also equal. Scalene Triangle: No sides are of equal length.None of the angles are equal. Based on ...
