Answer 2

$\fbox{ \fbox{ \bold{ \large{ \: triangles \: \: }}}}$

$\to$ A figure enclosed by three line segments is called a Triangles

$\to$ Triangles has 3 angles and 3 sides

$\bold{ \large{ \fbox{ \fbox{ \: \: Classification \: of \: Triangles \: \: }}}}$

$\bold{ \underline{ \: According \: to \: the \: length \: of \: their \: sides \: \: \: }}$

$\to$ Scalene triangle - the triangle having all the sides of different lengths is called scalene triangle

$\to$ Isosceles triangle - the triangle whose any two sides are equal is called isosceles triangle

$\to$ Equilateral triangle - the triangle whose all sides are equal is called equilateral triangle

$\bold{ \underline{According \: to \: the \: measures \: of \: their \: angles \: \: \: }}$

$\to$ Acute angled triangle - the triangle in which each angle is a cube is called acute angled triangle

$\to$ Right angled triangle - the triangle whose one angle is 90 degree is called right angled triangle

$\to$ Obtuse angled triangle - the triangle in which only one angle is obtuse is called obtuse angled triangle
