1) ABCD là HBH thì:
\(\overrightarrow{AB}=\overrightarrow{DC}\)\(\Leftrightarrow\) \(\left(1;-5\right)=\left(-2-x_D;1-y_D\right)\)
\(\Leftrightarrow\) \(\hept{\begin{cases}-2-x_D=1\\1-y_D=-5\end{cases}}\)\(\Leftrightarrow\) \(\hept{\begin{cases}x_D=-3\\y_D=6\end{cases}}\)
2) Bạn chuyển hết vế phải qua vế trái

When I was little, I watched an animated movie called: "1001 Dalmatians". This movie is so good it captivated me that I couldn't miss an episode. It is a movie about 1001 Dalmatians. The main character is an evil old woman who likes to use the fur of dogs to make wonderful clothes. The film has both sad and funny scenes, so many children around the world love to watch it. And me too, I love watching this series and love the cute blobs too.
