What’s a reduction?

In the kitchen, the term “reduction” refers to a technique that delivers intensely flavored, thickened liquid simply by boiling. Whether it is a soup or a sauce, by bringing the liquid to a rapid boil, it turns into steam and escapes from the pan, in turn reducing its original volume.

How do you explain enlargement?

Enlargement is an example of a transformation. A transformation is a way of changing the size or position of a shape. To enlarge a shape, a centre of enlargement is required. When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.

What is scale enlargement?

You already know that the size of an enlargement is described by its scale factor. For example, a scale factor of means that the side-lengths of the new shape are twice the side-lengths of the original. A scale factor of means that the side-lengths of the new shape are three times the side-lengths of the original.

How do you enlarge by a scale factor of 2?

2) If the scale factor is 2, draw a line from the centre of enlargement, through each vertex, which is twice as long as the length you measured. If the scale factor is 3, draw lines which are three times as long. If the scale factor is 1/2, draw lines which are 1/2 as long, etc. The centre of enlargement is marked.

What is the difference between open reduction and closed reduction?

Reduction could be by “closed” or “open” methods: Open reduction is where the fracture fragments are exposed surgically by dissecting the tissues. Closed reduction is the manipulation of the bone fragments without surgical exposure of the fragments.

How do you find an enlargement?

To find the centres of enlargement, draw lines through the corresponding corners of each shape. These lines will cross at the centre of enlargement, as shown below. The centres have been marked with the letter O in both diagrams.

What is a scale reduction?

When Scale Factor is between 0 and 1, the new shape is a reduction (smaller). Or less than 100%. When Scale Factor is above 1, new shape is an enlargement (bigger).

What are the 3 types of scale?

Three Types of Scale:Fractional or Ratio Scale: A fractional scale map shows the fraction of an object or land feature on the map. … Linear Scale: A linear scale shows the distance between two or more prominent landmarks. … Verbal Scale: This type of scale use simple words to describe a prominent surface feature.More items…•

What is the scale factor of reduction?

The scale factor describes the size of an enlargement or reduction. For example, a scale factor of means that the new shape is twice the size of the original.

Should you stir while reducing?

Stirring redistributes the heat more effectively. If left alone, heat has to rise to the top and liquid on top that is less hot will have to find a way to migrate down the heat column. … If you were to reduce a smaller volume stirring on higher heat will accomplish it much faster.
