Angles...
Given : , AB + BC + AC = 12 cm.
We know that the sum of interior angles of a triangle is
Sum of two angles is less than
Also, sum of all the sides is given as 12 cm, which does not contradict any property of a triangle.
Hence this type of triangle can be constructed.
Therefore the given statement is True.
Answer
False
Solution
Given : , AB + BC + AC = 10 cm.
We know that the sum of interior angles of a triangle is 180°.
But here
The sum of two angles is greater than which is not possible.
Hence, this type of triangle can’t be constructed.
Therefore the given statement is False.
