Question

notice/wonder
what do you notice? what do you wonder?
write at least two statements for each question.
i notice...
i wonder...

Explanation:

Para "I notice..." se pueden identificar relaciones de proporcionalidad entre segmentos (ej: $\frac{AD}{AB} = \frac{3}{3+9} = \frac{1}{4}$ y $\frac{AE}{AC} = \frac{5}{5+15} = \frac{1}{4}$) o que $DE = 4$ y $\frac{BC}{4} = \frac{16}{4} = 4$. Para "I wonder..." se pueden plantear si $DE \parallel BC$ o si los triángulos $ADE$ y $ABC$ son semejantes.

Answer:

I notice... that $\frac{AD}{AB} = \frac{AE}{AC} = \frac{1}{4}$; I notice... that $DE = 4$ and $BC = 16$.
I wonder... if $DE$ is parallel to $BC$; I wonder... if triangles $ADE$ and $ABC$ are similar.
