1. Applying Similar Triangles to the Real World
 Similar triangles can be used for many different things. In architecture similar triangles are used to represent doors and how far they swing open. Also when you use shadows that make triangles to find the height of an object. You can use that find the height of actual objects and they can also be used to stabilize a bridge.

3. Similar triangles can be used for many different things
Similar triangles can be used for many different things.  It can be used to stabilize a bridge. It is used in aerial photography to see the distance from the sky to the ground. It is used in construction to measure out the room and scale size. It is used in light beams to see the distance from light to the target. The Wright Brothers used similar triangles to prepare their landing. Mohamed Ali

4. You can use similar triangles for a variety of things
You can use similar triangles for a variety of things. You can use it to find an objects shadow or you can use it to get an objects height. You can also use this method to find the heihgt of a ramp. You can also use triangles for engineering, architecture, and useful in heights.

5. Similar triangles can be used to find the length or height of certain things. You can used them to find out the length of shadows, people and buildings. An example would be that if you are beside a building and the building casts a shadow of 35ft. Your shadow is 8ft long and your height is 5ft. You can set a proportion to figure out the building's height. This is another example:
"Find the value of the height, h m, in the following diagram at which the tennis ball must be hit so that it will just pass over the net and land 6 meters away from the base of the net.“
