Answer 2

Type of triangles are classified as :-

$\large{\sf{\green{\underline{ Based~ on~ length~ of ~their~ sides}}}}$

• According to the length of sides, triangles are classified into 3 types.

1. Scalene triangle: Triangle are said to be scalene when none side of triangle is equal to another side of same triangle.
2. Isosceles triangle: Triangle are said to be isosceles when length of two side of same triangle is equal
3. Equilateral triangle: Triangle are said to be equilateral when all sides of triangle are of equal measures.

$\large{\sf{\green{\underline{ Based ~on~ measures ~of ~angles}}}}$

According to the measures of angles of triangle, triangle is classified into 3 types :

1. Acute triangle: Triangle are said to be acute angled triangle when all sides of triangle is less than 90°
2. Obtuse triangle: Triangle are said to be obtuse when the one angle of triangle is greater then 90°
3. Right triangle : Triangle are said to be right angled triangle when one angle of triangle is equal to 90°.
