Description: The topic of Triangles is the most important in Geometry. In this video, let us learn all about the four types of triangles: right-angled, equilateral, isosceles, and scalene triangles.

Question

Classify the following triangles according to their sides.

Accepted Answer

According to the measure of sides, triangles are classified into three.
$\to$ Equilateral triangle
Having all the three sides equal.
$\to$ Isosceles triangle
Having two sides equal and base different.
$\to$ Scalene triangle
Having all sides different.

Now let us consider each of the given triangles and analyse which type it belongs to.

Consider $△ A B C$
$A B = 5 cm$
$BC = 8 cm$
$CA = 8 cm$
As the two sides of the triangle are equal, it is an isosceles triangle.

Consider $△ N E T$
By observing the figure we can see that all the three sides are different.
Hence, this is a scalene triangle.

Consider $△ L M N$
By observing the figure we can see that two sides of the triangle are equal.
Hence, this is an isosceles triangle.

Consider $△ F G H$
By observing the figure we can see that all the three sides are equal.
Hence, this is an equilateral triangle.

Consider $△ R S T$
By observing the figure we can see that two sides of the triangle are equal.
Hence, this is an isosceles triangle.

Consider $△ P Q R$
By observing the figure we can see that two sides of the triangle are equal.
Hence, this is an isosceles triangle.

Classify the following triangles according to their sides.
