Triangle Angles Triangle Design Classifying Triangles Similar Triangle classification by angles. that is, we must first identify what types of angles make up a triangle before we can determine whether it is an acute, equiangular, obtuse, or right triangle. let’s take a closer look at each type of triangle that results from classifying triangles by their angles. this tells us that one of the three angles. On the basis of sides, triangles are classified into 3 types. equilateral triangle: when all three sides have the same length, the triangle is considered to be an equilateral triangle. isosceles triangle: if two sides of a triangle are equal, it is called an isosceles triangle. scalene triangle: if all the sides of a triangle are of different.

Classifying Triangles Video Lessons Examples And Solutions Triangles are classified by their angles and their sides. all angles in an acute triangle measure < 90 ∘. < 90 ∘. one of the angles in a right triangle measures 90 ∘, 90 ∘, symbolized by . one angle in an obtuse triangle measures between 90 ∘ 90 ∘ and 180 ∘. 180 ∘. sides that have equal length are indicated by the same hash marks. Types of triangles based on angles. triangles can be classified into three types with respect to their interior angles which are: acute angled; obtuse angled; right angled; let us discuss them. acute triangle. an acute triangle is a triangle whose all the three interior angles are acute. in other words, if all interior angles are less than 90. The types of triangles classified by their angles include the following: right triangle: a triangle that has a right angle in its interior (figure 4). figure 4 right triangle. obtuse triangle: a triangle having an obtuse angle (greater than 90° but less than 180°) in its interior. figure 5 shows an obtuse triangle. figure 5 obtuse triangle. Equilateral . equiangular triangle. a triangle where all three sides are of equal. length and all three angles the same (60º). right angled triangle. a triangle with one right angle (90º) obtuse triangle. a triangle with an angle greater than 90°. to test your knowledge on different types of triangles, have a look at our videos, interactive.
