VERTICAL ANGLES--- directors chair

Here we have a nice leather directors chair. The chair is black as most of them are wood, painted black. Directors chairs are a perfect example of vertical angles. As you close the chairs, the angles formed by the base of the chair always remain vertical. Since vertical angles are always congruent, if you open up this chair more and try to make it taller the green angles will increase and still be the same on both sides. The red angles will decrease but still be vertical to eachother. I found this picture of a directors chair on the internet. My dad used to own a directors chair when i was a little boy but my little brother broke it! Director chairs are used for directors to sit in and be comfortable. The best part about director chairs is that they are customizable. Its some peoples jobs to make sure the chair is set to the perfect hieght for the director. The director is supposed to be able to jump in and out of his seat very quickly. Director chairs are also used as just regular chairs. I have been to houses before where people just sit in directors chairs.
