1. ## angles

stuck on the both parts. im trying to prove |ab| is bigger than |bd| so that must mean angleADB is bigger than angleAEB

2. ## Re: angles

Hey markosheehan.

What have you tried? Can you show us your working?

3. ## Re: angles

reference the attached diagram ...

$\color{red}{d = e + f}$ ... why? what's that tell you about the relative measures of $\color{red}{d}$ compared to $\color{red}{e}$?

$\color{red}{e = g + c}$ ... why? what's that tell you about the relative measures of $\color{red}{e}$ compared to $\color{red}{c}$?

finally, does the transitive property work for inequalities?

4. ## Re: angles

Can you say that cause d=e+f so angel d has to be bigger than f

5. ## Re: angles

since each angle measure is positive, $d = e + f \implies d > e \text{ and } d > f$

you still haven't said why $d = e + f$ ...

6. ## Re: angles

as they are exterior angles (sum of the interior interior angles equal the exterior angles) thanks
