How you can use a ratio to enlarge or reduce a figure.?
Suppose the ratio is R.Select a side of the first figure. Suppose its length is L1. Draw a line that is L1*R units long.At the end of the line, draw an angle congruent to that on the first figure.Suppose the second side of the first figure is L2. In the second figure, draw a line that is L2*R units long.Continue in the same way all round the figure.
When you enlarge something on a photocopy machine is that image a dilation?
Yes, when you enlarge an image on a photocopy machine, it can be considered a dilation. Dilation in geometry refers to the transformation that changes the size of a figure while maintaining its shape and proportions. In the case of photocopying, the enlarged image retains the same shape and relative dimensions as the original, making it an example of dilation.
Why are dilations similar to scale drawings?
Dilations are similar to scale drawings because both involve resizing an object while maintaining its proportional dimensions. In a dilation, each point of the original figure is moved away from a center point by a scale factor, resulting in a similar figure that retains the same shape. Similarly, scale drawings use a specific ratio to enlarge or reduce the size of an object, ensuring that all dimensions remain proportional. Thus, both processes create figures that are geometrically similar.
Words that mean the same as accrue?
Increase, accumulate, grow, amass, enlarge, collect, gather...
How do you deduct a minus figure from a plus figure?
It's the same as adding the same figure without the minus figure. '+' minus '-' = '+'
When you enlarge or reduce a figure what are the features that stay the same?
the angles stay the same but the lenght of the sides change.
Why do the angles stay the same if you enlarge or reduce a figure?
Because the figures are said to be similar to each other and retain the same angles

What is a similar plane figure?
It is a figure that is the same as another figure in the plane. A square is the same plane figure as another square, but a cube is same the same plane figure even tho it is made up of 6 squares.

What is the eidograph?
An eidograph is a mechanical device used to reduce or enlarge the scale of a drawing or make a copy of a drawing at the same scale. It is similar in use to a pantograph, but was generally considered to be more accurate. It was invented by an Englishman in the 1820's and was used into the early 1900's.
What does the word enlarge mean?
The word "enlarge" means to make larger, or to become larger. A company may enlarge its warehouse to store more goods, or an infection could cause a lymph node in the body to enlarge.When used for images, the word enlarge means to "blow up" or increase in scale so as to display more detail. A photographic enlargement is the same photo in a larger size.
How were the geographical features of the New England colonies related to these industries?
they were related by useing the geographical features to work in indstries like the good coastalhardbord for trading and fishing.
In maths how do you enlarge a shape by the scale factor of 1?
if you multiply all the points by one you get the same points so the shape stays the same.
