Chapter 3: Q38. (page 115)

If M is the midpoint of $\bar{A B}$ andAM=12 thenAB=▁(?).

Short Answer

Expert verified

If M is the midpoint of $\bar{A B}$ , then $A B = 24$ .

Step by step solution

Step 1. Find the property of the midpoint of a line in geometry.

The midpoint divides the line into two equal halves.

Step 2. Use the property.

M is the midpoint of $\bar{A B}$ . So, Mdivides $\bar{A B}$ into two equal parts such that $A M = M B$ or $A B = 2 A M$ .

Step 3. Calculate the length of the line.

$\begin{matrix} A B = 2 A M \\ = 2 \times 12 \\ = 24 \end{matrix}$

Therefore, the length of $\bar{A B}$ is 24.
