On the basis of the length of the sides, triangles are classified into three categories.
Scalene Triangle
If all the sides are different in length, then the triangle is Scalene Triangle.
Isosceles Triangle
If two sides are the same in length, then the triangle is Isosceles Triangle.
Equilateral Triangle
If all the sides are the same in length, then the triangle is Equilateral Triangle.
Identify each triangle based on sides.
Problem 1 :
Solution :
By observing the figure,
AB = BC = AC = 2yd
Since all the sides are equal in length, it is an
Equilateral Triangle
Problem 2 :
Solution :
By observing the figure,
AB = 7 in, BC = 5 in, and, AC = 3 in
Since all the sides are different in length, it is an
Scalene Triangle
Problem 3 :
Solution :
By observing the figure,
AB = 5 ft, BC = 3 ft, and, AC = 3 ft
Since the two sides are the same in length, it is an
Isosceles Triangle
Problem 4 :
Solution :
By observing the figure,
AB = 3 in, BC = 2 in, and, AC = 2 in
Since the two sides are the same in length, it is an
Isosceles Triangle
Problem 5 :
Solution :
By observing the figure,
AB = BC = AC = 4 ft
Since all the sides are equal in length, it is an
Equilateral Triangle
Problem 6 :
Solution :
By observing the figure,
AB = 7 yd, BC = 9 yd, and, AC = 8 yd
Since all the sides are different in length, it is an
Scalene Triangle
