6th 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 you enlarge or reduce an object the thing that will stay the same is the shape of the original object because all you are doing to it is that your just blowing it up or shrinking its size the thing that will change is the size because you are either making the original object bigger or smaller

When you enlarge or reduce a figure the area, perimeter, side lengths are all going to CHANGE! This is because if you enlarge or reduce the shape it will either grow bigger or smaller so that will have to shrink or stretch. On the other side the angles are all going to STAY the same. This is because if you measure one shape then measure the same one just bigger, the protractor won’t stretch too it will stay the same as of the angles.

When you enlarge or reduce a figure the perimeter and the area change, but all of the angles stay the same. When it says two shapes are SIMILAR it means "Same shape but different size".

If you were to change the size of a shape, the shape would stay the same. If you enlarge or reduce the shape, the perimeter and area increase, but the shape still stay the same.

If you enlarge or reduce a figure the perimeter, area, and side lengths will all change, but the angle measurements will stay the same. If two shapes are similar than the shape is the same, but not the size.

When you enlarge or reduce a figure the angles stay the same and the shape stays the same. The thing that changes is the side lengths and the area. Two shapes are similar if they are the same shape and if the angles are the same. However they will be different sizes.

When you enlarge or reduce a figure only the angles stay the same. The side lengths, area and perimeter change when you enlarge or reduce a figure. Two shapes are similar if they are the same shape but different size.

When you enlarge or reduce a shape it still has a lot of the same features. Like the angles stay the same no matter what even if you turn it sideways. The shape of the figure stays the same it is just bigger or smaller. When someone says that the shapes are similar they mean. They have the same size and angles not shape. If they were the same shape they would be called identical shapes.

When you enlarge a figure, the area and perimeter change. The area, at least in our cases, changed by about four and the perimeter changed by about two. The angles however, did not change. They stayed the same no matter how large or small you made the figure. In order for two shapes to mathematically be considered similar, they have to be of identical shape, but of different size. Now you know.

when you enlarge or shink a object the angles stay the same.But the size can variey.Also to say a shape is simailar means saying they are relative to each other.They have alike sides, no that does not mean they have the same exact sides.

When you enlarge or reduce the figure, the angles stay the same. The general overall shape also stays the same but the size changes. The one features that change is the size of the area in the shape. The other features the change are the line segments and the perimeter. When a shape is enlarged or reduced it is similar to the original image. Similar means that it is the same shape but a different size.

When you enlarge or reduce a figure, the figure has the same angles because the figure is the same but just a different size. Also the shape will just get larger so when you measure with a protractor the angles are the same the lines are just longer and wider. What will change are the size, length, width, height, perimeter, and area. These features change because when you enlarge or reduce something they stretch or shrink so they will be longer, wider, or shorter. Two shapes are similar if the shape and angles are the same but the size is different.

when you inlarge or reduce a figure the size changes but the shape stays the same

When you reduce or enlarge a figure then the shape will stay the same. But the size will either reduce or enlarge. Like with the rubber band experiment. The shape of the man enlarged but still is the same shape, but the size enlarged by two for the side lengths and by 4 for the area.

When you enlarge or reduce a figure, the shape will stay the same but, the size of the shape will change. For example, if you reduce your shape the size will get smaller but the shape will stay the same. Two shapes are similar if they have the same shape but not the same size.

Two shapes are similar when they are the same shape but different sizes

Unknown said...

When enlarging or reducing a figure the features that will stay the same is the shape and the angles. The features that will change are the size, the area, and the perimeter. Two shapes are similar if they have the same shape but different sizes.

When I enlarge or reduce the figures the angels and the shape stays the same. When I enlarge or reduce the figure the size changes and so do the base, height, length, perimeter, and the area. When two shapes are “similar” it means they have the same shape but different size. For example Mrs. Ryon and I are similar too each other: same gender, different size.

When you enlarge or reduce a figure,the angles stay the same. The lengths of the height and width change.The area and the perimeter also change. Two shapes are similar if they have the same shape,but different side lengths.

When you enlarge a figure or reduce a figure the angles will always stay the same. If they are relative then they will have the same sides, but probably have different side measurements if it is enlarged or reduced. The perimeter and area will change and the term "when the two shapes are SIMILAR" it means same shape but different size.

Unknown said...

When you reduce a figure, or inlarge a figure the angles will be the at the same degree they were at before. If they are relative, they will have different side measurements, but the sides will be the same. If two shapes are similar it indicates that they are the same shapes, theyre just different sizes.

Dilan Samarasuriya said...

One ways its similar is the shape. Even though it’s changed in size, it stays same in shape meaning it’s similar. Another similarity is the angles. Whenever you enlarge or shrink an object, the side lengths and measurements are different. But the angles of the object are equal to the newly created image. Two shapes are similar if they are the same shape and same angles.

When you enlarge or reduce a figure the side lenghts, area, and perimeter change. While the angles, and shape stay the same.
