Geometry
We are learning to:
• Describe features of 2 and 3D shapes.
• Measure and make nets for containers.
• Identify angles, perpendicular, parallel and
vertical lines.
• Draw and interpret scale maps.
• Give clear directions to follow paths between
positions in maps and mazes.
• Describe and follow directions using
compass points.
• Enlarge a shape to scale.
Name the shape

Angles:
• What is an angle?
• An angle is the amount of
turn
• What unit is used to
measure the amount of turn? • Degrees (°)
• ¼ turn is …
• ½ turn is …
• ¾ turn is …
• Full turn or a circle is…

360°
Two lines are needed to form an angle.
Right Angles
A right angle is a turn of 90°
(90 degrees)
How do we show a right angle?
Activity 1
• Make a setsquare by following the
instructions on p. 189 in your textbook.
• Work with a friend and predict what angles
are right angles. Use the setsquare to test
your predictions.
• Find examples of perpendicular lines.
Draw at least two examples of
perpendicular lines. [Remember the date
and heading]
PARALLEL LINES
• What are parallel
lines?
• Lines that are always
the same distance
apart.
• How do we show
lines are parallel?
• How do we write it
when lines are
parallel?
• AB║CD
PERPENDICULAR LINES
• What are they?
• How do we show lines
are perpendicular?
• Two lines meeting or
crossing at a 90°
angle (right angle)

• How do we write it when
lines are perpendicular?
• AB ┴ CD
TASK
• Use the digital camera and take a photo
of:
• Parallel lines
• Perpendicular lines
• Right angles
• Lines – horizontal, vertical and diagonal
