RIGHT ANGLES
AN ANGLE IS WHERE 2 LINES MEET WHEN CREATING A SHAPE
A RIGHT ANGLE • A right angle is the corner of a square or rectangle • Angles are measured in degrees – ° 90º in a right angle
WE USE THESE RIGHT ANGLES TO DESCRIBE TURNS… Four turns Three turns One turn Two turns
WE ALSO NEED TO KNOW WHICH WAY TO TURN ! If it moves in the same direction as the clock hands it is called CLOCKWISE
WE ALSO NEED TO KNOW WHICH WAY TO TURN! If it moves in the opposite direction to the clock hands it is called ANTI-CLOCKWISE

DO YOU REMEMBER THE COMPASS POINTS?
WHERE AM I? If I face South and make one right angle turn clockwise, where will I face?
WHERE AM I? If I face South and make one right angle turn clockwise, where will I face?
WHERE AM I? If I face East and make one right angle turn anti clockwise, where will I face?
WHERE AM I? If I face East and make one right angle turn anti clockwise, where will I face?
WHERE AM I? If I face North and make 2 right angle turns anti-clockwise, where will I face?
WHERE AM I? If I face North and make 2 right angle turns anti-clockwise, where will I face?
WHERE AM I? If I face East and make 2 right angle turns clockwise, where will I face?
WHERE AM I? If I face East and make 2 right angle turns clockwise, where will I face?
HOW MANY RIGHT ANGLE TURNS? If I faced East and now face South, how many clockwise right angle turns did I turn?
HOW MANY RIGHT ANGLE TURNS? If I faced East and now face South, how many clockwise right angle turns did I turn?
