Decide whether it is possible to construct a triangle with the given side lengths. explain your reasoning. 5cm , 7cm , 12cm

There is one theorem in triangle which states that sum of any two sides of a triangle is greater than the third side. For example, if a,b and c are three sides of a triangle, then a+b>c, b+c>a and a+c>b.

So, we will use here same concept.

Let a=5cm, b=7cm and c=12cm

a+b = 5+7 = 12cm which is equal to c.

But a+b should be greater than c.

Therefore, the triangle doesn't exist.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
