5th period reflection - 10/22/10

When you enlarge or reduce a figure, what features stay the same? What features change?


What does it mean for two shapes to be SIMILAR? ("Two shapes are similar if...")

When reducing or enlarging a figure, some features stay the same, but some also change. For example, then angles of the figure(s) and the shape always stay the same. But the perimeter, area, circumference, radius, diameter, measures of sides and size differ when reducing or enlarging a figure.
For two shapes to be similar, it means that they are almost identical because they have the same shape just a different size. They also have the same relative area where they are located.

When you enlarge or reduce the size of a shape many things will stay the same. The shape of it will stay the same because you’re changing the size. The angles will also stay the same because you aren’t changing the shape of the shape. The size although will change because that’s what you are changing when you enlarge or reduce the shapes size. You wouldn’t be changing that many things but you would change the area and the size of each line in the shape because you’re changing the size of it. If things are similar that means that the shapes are the same shape or have the same number of lines but the size could be different to make them not look like the same size as the other shape.

When you enlarge or reduce a shape, the angle measurements and the figures stay the same, but the side lengths change.

Two shapes are similar if they are the same shape, but different sizes.

When you enlarge or reduce a figure, bassicly the size changes. The width, the height, and the length either get bigger or smaller. What stays the same is the angles. Two shapes are similiar if the they have the same figure or shape. The angles also need to be the same basic shape and also the degrees of the angles.

When you enlarge or reduce a figure or object the angles stay the same. The things that change are the perimeter and area, and how long each side length is. When two shapes are similar it means they are the same shape but different sizes. For example you have the exact same triangle one is bigger than the other .You could say those shapes are similar.

when you enlarge or reduce a figure the only thing that stays the same is the angles and the shape of the figure because all corresponding angles are the same. the things that changes is the size of the side lengths and the shape of the figure.for two shapes to be similar they have to be the same shape but not the same size

(this is my new one cuz I wanted to change my first one but it wouldn't let me)

When you enlarge or reduce a shape, the angle measurements and the shape of the figures stay the same, but the side lenghts of the reduced or enlarged figure changes. The angle measurements stay the same, because you're not changing the shape of the figure, and the side lengths change because you're either making it bigger or making it smaller.

For two shapes to be similar, they need to be almost identical, have to be the same shape, and also need to be different sizes.

There is one thing that stays the same when you enlarge or reduce a figure. The angles stay the same. Even if you reduce the a figure with a 90 degree angle, the smaller image will still have that same angle. The angles do no change because even though you are getting bigger, the angle does not move because it is still the same shape it is the same if you are enlarging too. Also, two shapes are similar if thy are almost identical and they are the same shape but a different size.

The corresponding angles will always stay the same. The shape of the object will also stay the same. The side lengths will change, which also affects the perimeter and area. Those things will also change. If a shape is similar, then the shape will be the same, but the size will be different.

When you enlarge or reduce a shape there a few things that stay the same, and there are a few things that don’t stay the same. One thing that stays the same is the angles, no matter how much you reduce it or enlarge it the angels will always stay the same. Another thing that stays the same is the basic shape itself because whenever you enlarge or reduce your object your image will look somewhat like it. Now onto things that don’t stay the same, whenever you reduce or enlarge the area and perimeter change because that is based on the size of your image. Of course a real no brainer is whenever you reduce or enlarge your object the image’s side lengths will not be the same. So all of this basically comes to is saying that whenever two shapes are similar this would be some of the “rules” I guess you could say. Also there is a simple six letter way would be: similar means same shape different size.

When you shrink or enlarge a figure the shape and angles stay the same, but the size changes. The shape might be bigger or smaller, but the angle measures will stay the same.
The shape that you shrunk or made bigger is similar to its image. Two shapes are similar if their shape is the same, but their size is different.

When reducing or enlarging a figure, there are things that change and stay the same. Examples that change are the size of the shape and the side lengths. These things change because you are either making the shape bigger or making it smaller. Examples of things that stay the same are the shape because you haven’t changed it and the corresponding angles. If the angle degree for the object is 48 degrees on angle G then the corresponding angle on say angle K would also be 48 degrees.

For two shapes to be similar, they need to be almost identical, meaning that they need to be the same shape but different sizes.

When enlarging or reducing a figure, some shapes are going to change and so are not.But the shape angles will always stay the same it does not matter if it is reduced or enlarged.When reducing or enlarging a figure, some features stay the same, but some also change.The perimeter, area, circumference, radius,
diameter,and measurements of sides and size differ when you are reducing or enlarging a figure. For two figures to be similar is the same shape,different size.
