Slide 1 - Tekstslide

Learning goals 
At the end of this lesson I can:
  •  Identify supplementary angles
  • Identify complementary angles 
  • Use complementary and supplementary angles to find the value of unkown angles

Slide 3 - Sleepvraag

Starter
1. Are angles with sizes 37° and 53° complementary? 

2. What angle size is supplementary to 48°? 

3. Find the unknown value (y) 

Slide 4 - Tekstslide

Starter
1. Are angles with sizes 37° and 53° complementary? Why? 
Yes because they add up to 90°
2. What angle size is supplementary to 48°? 
The angle supplementary to 48° is 180° - 48° = 132° 
3. Find the unknown value (y) 
110° + 90° + y = 360°
y = 360° - 110° - 90°
y = 160°

Slide 5 - Tekstslide

Supplementary and complementary angles
Angles which add to 180° are Supplementary angles: 


Angles which add to 90° are Complementary angles: 

Slide 6 - Tekstslide

Supplementary and complementary angles
Angles which add to 180° are Supplementary angles: 


Angles which add to 90° are Complementary angles: 

Supplementary starts with the S of 'Straight angle'
Complementary starts with the C of 'Corner'

Slide 7 - Tekstslide

Supplementary and complementary angles
Angles which add to 180° are Supplementary angles:
