Scale Drawings with Angles: Aim
Understand that measurements in drawings can be calculated when we know the drawing’s angles.
Can construct scale drawings using angles and sides, to measure unknown sides.
Bearings: Aim
Understand that a compass points North, which we can use to navigate by picking different directions.
Can name the main directions and write bearings in 3 digit form.

Bearings Rules
1. Start from North
2. Measure Clockwise
3. Write 3 Figures
N = North
E = East
S = South
W = West
NE = North-East
SE = South-East
SW = South-West
NW = North-West
Bearing “to” vs. Bearing “of”:

Time Remaining:
"to":
from <start> to <end>
"of":
of <end> from <start>
