What is the difference between equilateral and scalene triangles?
What is the difference between equilateral and scalene triangles?
Equilateral triangle has all three sides equal in length. Scalene triangle has all three sides of different length.
What is isosceles and equilateral triangle?
An equilateral triangle is the one in which all the three sides are equal. It is a special case of the isosceles triangle where the third side is also equal.
What are the 3 main types of triangles?
According to internal angles, there are three types of triangles i.e., acute, right, and obtuse-angled triangle. According to the length of sides, triangles can be classified into 3 categories i.e., Scalene, Isosceles, and Equilateral triangle.
What is isosceles triangle and equilateral triangle?
What is scalene triangle?
A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.
What type of triangle has 0 equal sides?
scalene triangle
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.
What is the meaning of equilateral triangle?
Definition of equilateral triangle mathematics. : a triangle in which all three sides are the same length.
What is scalene triangle and isosceles triangle?
Types of Triangles by Length In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below). In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).
What is 180 degree triangle called?
straight angle-a 180 degree angle.
What type of triangle is ABC?
ABC in the given figure is an equilateral triangle, its all sides are equal. AB = BC = CA. (i) A triangle in which all the three angles are acute is called an acute angled triangle. ∠ABC, ∠ACB and ∠BAC are all acute angles.
What is an isosceles triangle?
An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.
What is called isosceles?
An isosceles triangle is a type of triangle that has any two sides equal in length. The two angles of an isosceles triangle, opposite to equal sides are equal in measure.
What is equilateral and scalene?
Equilateral: “equal”-lateral (lateral means side) so they have all equal sides. Isosceles: means “equal legs”, and we have two legs, right? Also iSOSceles has two equal “Sides” joined by an “Odd” side. Scalene: means “uneven” or “odd”, so no equal sides.
What are the 12 types of triangles?

What are the 7 types of triangles?
To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.
