Question

Match the triangle types in column $1$ with their properties in column $2$.

• A. $3$ equal angles
• B. $3$ unequal angles
• C. $2$ equal angles

Answer 1

On the basis of their angles, triangles can be classified into three different types as follows:

Equilateral: In this type of triangle, all the three angles are equal.

$m\angle A=m\angle B=m\angle C$

Isosceles: This type has two equal angles and the third angle has a different value.
$m\angle B=m\angle C\ne m\angle A$

Scalene: Scalene triangles are those which have different values for all $3$ angle.

$m\angle A\ne m\angle B\ne m\angle C$
