Figures are mathematically similar…

True or false:

Any two rectangles are similar. FALSE! For two figures to be similar all corresponding angles have to be congruent and the shapes have to share a scale factor.

Any two equilateral triangles are similar. True! For triangles to be similar it needs to have the same angles and a scale factor. The angles will always be the same. An equilateral triangle means all sides are the same length. If all sides are the same length that means that any other equilateral triangle will share a scale factor.

This is a neat page:

This is neat because:

It has good handwriting, it’s easy to read, has date and title, and it makes sense. A lot of my pages are like this besides one or two.

This is a bad page:

This is bad because:

It’s in multiple different pens, no pencil, not neat or organized, and messy handwriting.

In class, we learned a few different notations; similar~, corresponding <->, and congruent (equal sign with a similar notation on top). Then we learned what these notations are used for. This check up was to test our knowledge on that. They apply to scale factor, mathematical simirality, and a few other things.

On the front, we were supposed to find the similar shapes among a lot of rectangles and triangles. I did this by measuring the sides of the shapes and comparing to others to see if they had a scale factor. If they didn’t have a scale factor, they aren’t similar.

On the back, it showed us a reectangle and a triangle. For both the triangle and rectangle we had to draw a figure that was similar and not congruent, and we also had to draw a figure that was not similar to the given shape. For all of these we had to write why.
