Write True or False in each of the following. Give reasons for your answer:

A triangle ABC can be constructed in which B = 60°, C = 45° and AB + BC + AC = 12 cm.


True

Explanation:


Given, AB + BC + AC = 12 cm


B = 60° and C = 45°


We know that the sum of angles of a triangle is 180°.


But B + C = 60° + 45° = 105° < 180° which is possible.
