Revision angle pairs

Schedule: 

•  Learning goals
  
• Angle pairs on parallel lines
  
• Work 
• Counting game? 

Learning goals 

At the end of this lesson I can:

• Use the correct vocabulary for different angle pairs 
• Identify different angle pairs from parallel lines, cut by a transversal 

Angle pairs on parallel lines

1. Name an angle pair which is corresponding

- What property do these angles have? 
Equivalent, supplementary  or complementary? 

Angle pairs on parallel lines 

2. Name an angle pair which is Alternate (interior or exterior) 

- What property do these angles have?

Equivalent, supplementary or complementary? 

Angle pairs on parallel lines

3. Name an angle pair which is co-interior. 

- What property do these angles have?

Equivalent, supplementary or complementary? 

Angle pairs on parallel lines

4. Which other angle pairs do you know? 

- What property do these angle pairs have?

Equivalent, supplementary or complementary? 

Angle pairs on parallel lines

1. Corresponding angles (F-shape): 

∠IKJ & ∠KNM        ∠JKN & ∠MNP

∠IKL & ∠KNO         ∠PNO & ∠NKL

Corresponding angles are equivalent

2. Alternate angles (Z-shape): 

∠JKN & ∠KNO     ∠LKN &  ∠KNM

∠IKL  & ∠MNP     ∠IKJ   &   ∠ONP

Alternate angles are equivalent

Angle pairs on parallel lines

3. Co-interior angles (U-shape):  

∠JKN  & ∠KNM        ∠LKN  & ∠KNO

Co-interior angles add up to 180°

(Supplementary)

4. Other angle pairs: 

Vertically opposite (Equivalent) 

Co-exterior (Supplementary)

Finish work from the previous lesson

Open the LessonUp: Revision Measuring angles/Vertically opposite angles

Finish the work (on your level!!) From this LessonUp. 

The answerkey for the measuring worksheet is on ManageBac!

What to do

- I really want a challenge                                               Open the Pink slides on LessonUP

- I understand it, but I think a                                           Open the Blue slides on LessonUp

 bit more practice will help me                 

- I think more practice will help me,                              Open the Green slides on LessonUp

and would like to do more board work
