# Shapes and Such

“Two or more lines that meet at a point are called intersecting lines.”

“Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines.”

“Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times.”

Kaitlyn asked me to help her review her math last night for a test she has tomorrow, and it took me a second to realize what exactly she was studying.  Geometry.  In third grade.  I am fairly certain that when I was in third grade, we were not learning geometry yet.  At least not as in depth as what she seems to be learning; if we were taught geometry, it was very basic at best.

In addition to having to identify different angles (which was, surprisingly, what she had the most trouble with), she also had to identify different shapes.  Shapes that you and I might have to think twice about before we could positively identify.  Like a rhombus.  Kaitlyn had no trouble with identifying a rhombus at all.  Trapezoid?  No problem there, either.

Kaitlyn had little trouble with defining the different types of lines, too.  It did get a tad difficult when she had to try to picture whether lines on a trapezoid were parallel or intersecting, since they terminate at a defined point; I had to show her that to find out for sure, all she had to do was take her pencil and continue the lines, and she would have her answer.  It was like a light bulb went off in her head when I showed her that.  FSA testing continues today as well, and runs through Thursday.  I don’t think she will see much geometry on the math section though.
