Answer:
In the series on the basic building blocks of geometry, after a overview of lines, rays and segments, this time we cover the types and properties of triangles.
Definition: A triangle is a closed figure made up of three line segments.
simple triangle
A triangle consists of three line segments and three angles. In the figure above, AB, BC, CA are the three line segments and ∠A, ∠B, ∠C are the three angles.
There are three types of triangles based on sides and three based on angles.
Types of triangles based on sides
Equilateral triangle: A triangle having all the three sides of equal length is an equilateral triangle.
equilateral triangle
Since all sides are equal, all angles are equal too.
Isosceles triangle: A triangle having two sides of equal length is an Isosceles triangle.
isosceles triangle
The two angles opposite to the equal sides are equal.
Scalene triangle: A triangle having three sides of different lengths is called a scalene triangle.

Types of triangles based on angles
Acute-angled triangle: A triangle whose all angles are acute is called an acute-angled triangle or Acute triangle.
acute angled triangle
Obtuse-angled triangle: A triangle whose one angle is obtuse is an obtuse-angled triangle or Obtuse triangle.
obtuse angled triangle
Right-angled triangle: A triangle whose one angle is a right-angle is a Right-angled triangle or Right triangle.
right angled triangle
In the figure above, the side opposite to the right angle, BC is called the hypotenuse.
For a Right triangle ABC,
BC2 = AB2 + AC2
This is called the Pythagorean Theorem.
In the triangle above, 52 = 42 + 32. Only a triangle that satisfies this condition is a right triangle.
Hence, the Pythagorean Theorem helps to find whether a triangle is Right-angled.
