A QUADRILATERAL
A Quadrilateral has four-sides, it is 2dimensional (a flat shape), closed (the lines join
up), and has straight sides.

ABACUS 2
Pg. 32 Q1
Working with the teacher:
Use a geoboard to make
different quadrilaterals.
Discuss what angles you can
see;

Lesson 3: Symmetry
01-02-2017
L.O.To recognise and draw line symmetry in shapes
.I can draw the other half of symmetrical shapes.
I can draw lines of symmetry.
I know what symmetry is and can test shapes to see if they have line(s)
of symmetry.
Lesson 3: Symmetry
01-02-2017
L.O.To recognise and draw line symmetry in shapes
Symmetry is when one shape becomes exactly like
another if you flip, slide or turn it.
The simplest type of Symmetry is "Reflection" (or
"Mirror") Symmetry.
Lesson 3: Symmetry
01-02-2017
L.O.To recognise and draw line symmetry in shapes
Some shapes have more than one line of
symmetry.
What do you notice? How many lines of symmetry
do you think an octagon has?
Lesson 3: Symmetry
01-02-2017
L.O.To recognise and draw line symmetry in shapes
A regular polygon
has the same
number of lines of
symmetry as the
number of sides.
This does not
work for irregular
polygons however.
Can you guess
why?
