Entry 7:

Some common uses of similar triangles in real life range from nearly anything you can imagine, from trusses on houses, to sails on a sail boat. you can use this anytime something arises, and not just with triangles either! Let's say you own a sailboat,

Nice boat! but, lets say you need to buy a new sail,  the one you have ripped. So you order a new one online, but you get it, and it's too big!

Instead of returning it, because the company won't let you, you decide to cut it down to the proper size.

So, lets say that your sail is  6 feet tall, and 4 feet wide at the bottom.

So you take your sail, and measure a 4 foot wide base, and mark it, and go up on the altitude of the triangle six feet snd mark it. You knowbthat both triangles are righht triangles, and have an angle of 45 degrees. You make a lin going from the corner, to the six foot mark and cut it. that ins how you use similar triangles in a real life scenario!!
