transformation project By: harsimer aND ISABEL

In this project we will be showing and explaining translations, rotations, reflections, dilation's and symmetry. I hope you learn something in our presentation that you might not have known.

Dilation's- A dilation is when one object is made bigger or smaller than the original by the same scale factor. For example shape A is three times as big as shape B. The scale factor is 3.

The far right line above the word "Adidas" is twice as big as the far left one. This is an example of a dilation, the scale factor is 2.
For the 2 perfume bottles, the part of the bottle without the cap, the bigger bottle is twice the size of the smaller one without the caps.

Rotations- A rotation is when you rotate or turn something around a point of origin. The object spins around that point.

The fairs wheel represents a rotation because it is a circle and when it is in motion it can rotate in any direction and any degree.
The lock is very similar to the fairs wheel in the sense that it can rotate in any direction and any number of degrees. When you are putting in your combination the letters or numbers on the lock are rotating at a certain degree and direction.
The clock is also very similar to the 2 other pictures because the hands on the clock can rotate clockwise and in any number of degrees. There is also a number of gears on the inside of the clock that also rotate clockwise and counter-clockwise.

Symmetry- Symmetry is when two shapes are made up of the exact same parts and they will look the same no matter what you do to the shapes

The 2 shapes on the butterfly's wing, are symmetrical because if you lay them over top of each other they will look exactly the same.
The 2 half's of the heart are symmetrical because they are exactly the same, in shape and size.
The two half's of this cupboard are symmetrical because they are both rectangles and again if you lay them on top of each other there will be no overlap or anything.

Reflections- A reflection is a mirror image of a shape or object. It is reflected over a line and is the same on both sides. For example, you could reflect a shape over the x axis and it would be a mirror image of the original shape.

This is an example of a reflection because if you flip the blue shape over the middle line, it will reflect the same shape on the other side. It is exactly the same distance from the middle line.
This is another example of a reflection because the town on land is near the water and if you look at it from the right angle you will see a perfect reflection of the town in the water.
This is very similar to the last one because the swan is sitting on top of the water and you can see the water line where the image of the swan is reflected over.

Translations- A translation is when a shape or object is slid or moved in any direction. It will look the exact same as the original just in a different place.

This is an example of a translation because the car is changing lanes from the left lane over to the right lane. It is moving to the right and it is moving upwards.
This is a translation because when the escalator is moving downwards or upwards, the stair moves into the place in front of it or the place behind it, depending on the direction it is going.
An elevator is an example of a translation because when it is in motion it moves up and down, and when you translate something it can come up or down or left or right, in this case the elevator moves up or down.

In this presentation we showed and explained real life examples of translations, rotations, reflections, dilation's and symmetry. I hope you learned something you didn't know. Thank you for watching our presentation.
