In Math, we are learning about geometry. One thing we are mainly learning about is how to find out if to figures are ~ (similar), or not. We’ve discovered two different things two figures need to have in common in order for them to be similar. First, the corresponding angles must be congruent. In mathematical symbols, it would be the corresponding
‘s (angles) need to be ≅ (congruent). What this means is that each figure has an
that corresponds to another
. If each
that corresponds to the other
, then all of the corresponding
‘s are ≅. The next factor that decides weather or no a figure ~ another figure is the scale factor. The scale factor is one number that corresponding side lengths can be multiplied by to give corresponding side lengths to another figure. For example, a rectangle with a base of 5 and a height of 10 ~ a rectangle with a base of 10 and a height of 20, because the scale factor is 2 or 1/2. These two things you need to check are the ways you figure out weather or not a figure ~ another figure. Here is my worksheet. On the first page, we needed to identify which figures ~ other figures. On the second page, we needed to draw a rectangle that was ~ and NOT ~ the rectangle that was on the top of the page. Then we needed to do the same for triangles. Here is the check up:
