Question

question 2 1 pts a m b if you know that am = mb, what else is true? am = ab am = \frac{1}{2}ab ab = 2am ab = 2mb m is the mid - point of ab ab = mb

Explanation:

Step1: Recall mid - point definition

If a point $M$ on a line segment $\overline{AB}$ satisfies $AM = MB$, then $M$ is the mid - point of $\overline{AB}$.
Also, since $AB=AM + MB$ and $AM = MB$, we can substitute $MB$ with $AM$ (or vice - versa). So $AB=AM+AM = 2AM$ and $AB=MB + MB=2MB$. And $AM=\frac{1}{2}AB$ and $MB=\frac{1}{2}AB$.

Answer:

$AM=\frac{1}{2}AB$, $AB = 2AM$, $AB = 2MB$, $M$ is the midpoint of $AB$
