in abd bc is 12cm and ac is 5cm. what is the length of ba ?

To find the length of BA, we need to identify the triangle formed by points A, B, and C in relation to AB, BC, and AC.

Since you've mentioned AB = 12cm and AC = 5cm, we can deduce that A is the vertex connecting AB and AC. And B and C are the other two vertices of this triangle.

Now, we are tasked with finding the length of BA.

To do this, we can use the fact that the length of a line segment remains the same regardless of the order of the points used to define it.

In other words, BA is equal in length to AB. So, if AB is 12 cm, then BA will also be 12 cm.

Therefore, the length of BA is 12 cm.
