Match the following:

Measures of Triangle	Types of Triangle
(i) 3 sides of equal length	(a) Scalene
(ii) 2 sides of equal length	(b) Isosceles right angled
(iii) All sides are of different length	(c) Obtuse angled
(iv) 3 acute angles	(d) Right angled
(v) 1 right angle	(e) Equilateral
(vi) 1 obtuse angle	(f) Acute angled
(vii) 1 right angle with two sides of equal length	(g) Isosceles

Answer:

We know that, A triangle having three equal sides is called an equilateral triangle. A triangle having two equal sides is called an isosceles triangle. A triangle having all sides unequal is called a scalene triangle In a triangle, if each angle is acute angle then triangle is, called an acute angled triangle. If a triangle has a right angle, then it is called a right angled triangle. If a triangle has an obtuse angle, then it is an obtuse angled triangle. If a triangle has a right angle and two equal sides is called an isosceles right angled triangle. So, required matching is shown as below :

(i) 3 sides of equal length	(e) Equilateral
(ii) 2 sides of equal length	(g) Isosceles
(iii) All sides are of different length	(a) Scalene
(iv) 3 acute angles	(f) Acute angled
(v) 1 right angle	(d) Right angled
(vi) 1 obtuse angle	(c) Obtuse angled
(vii) 1 right angle with two sides of equal length	(b) Isosceles right angled
