Activities: Custom Category: Which One? Other Activities: Custom Category: Activities ![]() The content covered in this activity is also included in Congruence (Geometry - Unit 5). The problems require knowledge of the properties & theorems regarding isosceles and equilateral triangles.Ī set of teacher instructions is also included. Each incorrect answer has a phrase with it that tells you which bugs to eliminate. Each correct answer is paired with a trait that will allow the students to discover the bug in question. Students will answer each question according to the instructions. One of these bugs must be identified through the process of elimination. The 6 types of triangles can be listed as, acute triangle, obtuse triangle, right triangle, equilateral triangle, isosceles triangle, and scalene triangle.This is a quick and fun activity that is patterned after a famous children's game, Guess Who™. Which Types of Triangles Have Reflection Symmetry?Īll equilateral and isosceles triangles have reflection symmetry. Which Types of Triangles Have 3 Lines of Symmetry?Īll equilateral triangles have 3 lines of symmetry as three lines of symmetry can pass through the vertex of this triangle. ![]() Scalene triangle: If all the sides of a triangle are of different lengths, it is called a scalene triangle.Isosceles triangle: If two sides of a triangle are equal, it is called an isosceles triangle.Equilateral triangle: When all three sides have the same length, the triangle is considered to be an equilateral triangle.On the basis of sides, triangles are classified into 3 types. What are the Types of Triangles Based on Sides? Obtuse Triangle: When one of the angles of a triangle is an obtuse angle, it is called an obtuse-angled triangle.Right Triangle: When one angle of a triangle measures 90°, it is called a right-angled triangle.Acute triangle: In an acute triangle, all the angles measure less than 90°.On the basis of angles, triangles are classified into acute triangle, right triangle, and obtuse triangle. What are the 3 Types of Triangles Based on their Angles? Thus, there are six types of triangles in geometry. Based on their angles, the 3 types of triangles are listed as, acute triangle, obtuse triangle, and right-angled triangle. Based on their sides, the 3 triangles are classified as equilateral triangles, isosceles triangles, and scalene triangles. They can be classified according to 2 groups. There are six types of triangles in geometry. When all the sides and angles of a triangle are equal, it is called an equilateral or equiangular triangle.įAQs on Types of Triangles What are the Types of Triangles in Geometry?.The three internal angles in a triangle always add up to 180°.In an equilateral triangle, each of the three internal angles is 60°.Here is a list of a few points that should be remembered while studying the types of triangles: Acute Scalene Triangle : A triangle that has 3 unequal sides and 3 acute angles is called an acute scalene triangle. ![]()
