Solution

(i) A triangle has three sides.
(ii) A triangle has three vertices.
(iii) A triangle has three angles.
(iv) A triangle has six parts.
(Angles and sides are part of a triangle. So, three angles and three sides make six parts).
(v) A triangle whose no two sides are equal is known as Scalene triangle.
(A triangle whose length of all sides are different is called Scalene triangle).
(vi) A triangle whose two sides are equal is known as Isosceles triangle.
(A triangle whose length of two sides are equal is called an Isosceles triangle).
(vii) A triangle whose all the sides are equal is known as Equilateral triangle.
(A triangle whose length of all sides are equal is called an Equilateral triangle).
(viii) A triangle whose one angle is a right angle is known as Right angled triangle.
(A triangle whose one angle is 90° is called a Right angled triangle).
(ix) A triangle whose all angles measure less than 90° is known as an Acute triangle.
(A triangle whose all angles are less than 90° is called an Acute triangle).
(x) A triangle whose one angle is more than 90° is known as an Obtuse triangle.
(A triangle whose one angle is more than 90° is called an Obtuse triangle).
