Using Scale Drawings

Scale drawings are a good example of how similar shapes are used in the real world.[br][br]The scale drawing is either an enlargement or dilation (reduction) of the real life object.[br][br]Large objects, like houses and cars, are drawn smaller by dividing by a scale factor.[br]Another example of this is maps of towns and countries.[br][br]Very small objects, like insects or computer chips, can be drawn as enlargements so that we can better see their details.[br][br][br][color=#0000ff][size=200]Written Work - copy the following notes into your workbook.[/size][/color]
