CLIL SINERGY 2017 ANIMALS… LOVE THE DIFFERENCE!
LET’S BEGIN WITH THE GLOSSARY: It’s a line What’s it? Wehavedifferentkindsof LINES !
CURVED line STRAIGHT line BROKEN line DOTTED line OUTLINE LINE SEGMENT
… AND NOW LET’S TALK ABOUT SHAPES: a SHAPE maybe ROUND/CIRCLE SQUARE RECTANGULAR TRIANGULAR OVAL
A QUADRILATER has four-sides, it is 2-dimensional (a flat shape) closed (the lines join up) hasstraight sides. Four sides (edges) Four vertices (corners) The interior angles add up to 360 degrees QUADRILATERAL
LET’S LOOK CLOSELY AT A SQUARE
IT’S A SQUARE Ithasequalsides everyangle is right angle (90°) oppositesides are parallel ithastwodiagonals A polygon’s diagonals are line segments from one corner to another (but not the sides)
= FOUR VERTICES = FOUR STRAIGHT SIDES = TWO DIAGONALES
The red line down the center is theLine of Symmetry Folding Test You can findif a shapehas a Line of Symmetry byfoldingit. When the folded part sitsperfectly on top (alledgesmatching), then the fold line is a Line of Symmetry. THE SQARE hasgot 4 lines of simmetry
