Similar and Congruent Figures
Similar and Congruent FiguresObjective: To understand similar and congruent figures.
Similar and Congruent FiguresCongruent Figures - Figures that have the same size and shape.
Similar and Congruent FiguresCongruent Figures - Figures that have the same size and shape.
Similar Figures - Figures that have the same shape but not same size.
Similar and Congruent FiguresIf one shape can become another using rotation.
Similar and Congruent Figuresreflection
Similar and Congruent FiguresOr translation, then the two shapes are called Congruent:
Similar and Congruent FiguresThe parts of congruent figures that match are called corresponding parts.
Similar and Congruent FiguresSometimes it can be hard to see if two shapes are Similar, because you may need to turn, flip or slide one shape as well as resizing it.

Similar and Congruent FiguresA Tessellation (or Tiling) is when you cover a surface with a pattern of flat shapes so that there are no overlaps or gaps.
Similar and Congruent FiguresA regular tessellation is a pattern made by repeating a regular polygon.
Similar and Congruent FiguresA vertex is just a "corner point".
Similar and Congruent FiguresThree hexagons meet at this vertex,and a hexagon has 6 sides. So this is called a "6.6.6" tessellation
Similar and Congruent FiguresA semi-regular tessellation is made of two or more regular polygons. The pattern at each vertex must be the same!
