SCALE FACTOR

Case analysis:

A scale drawing of a thing is exactly the exact same shape at the item but an alternate size. The grade of a drawing can be actually a contrast of this span utilized on a drawing into the span that it represents. The scale will be written like a ratio. The ratio of 2 corresponding sides in similar amounts is known as the scale variable

Scale variable = span in image / corresponding span in thing

If one contour could grow to be the following with revising, then a contours are alike. Thus, two contours are similar if it’s possible to grow to be one opposite after a resize, flip, twist or slide. From the photo below showing the negative view of a search engine. Scale variable is 1:200

which usually means that a period of 1 cm over the photo above corresponds to some period of 200cm or two m, of their true engine. The scale may be written as the ratio of 2 spans.

inch . ) In case the amount of the version is 11cm, subsequently a total length of this engine at the photo above( such as the couplings (mechanism utilised for connecting ) will be:

a) 22cm

b) 220cm

c) 220m

Id ) 22m

Response: a)22m

2. What’s going to influence the similarity of any two polygons?

a) They’re reversed

b) They’re dilated by a scale variable

c) They’re clicked

Id ) They aren’t the mirror image of the other person.

Response: d)They aren’t the mirror image of oneanother

3. What’s the true diameter of this doorway if the diameter of this doorway in photo is 0.35cm?

a) 0.7m

b) 0.7cm

c) 0.07cm

Id ) 0.07m

Response: a)0.7m

4. In case two similar triangles possess a scale variable 5:3 which announcement about both triangles holds true?
