Revision angle pairs
Schedule:
•  Learning goals
• Angle pairs on parallel lines
• Work
• Counting game?

#### Slide 1 -Tekstslide

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

#### Slide 2 -Tekstslide

Angle pairs on parallel lines
1. Name an angle pair which is corresponding

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

#### Slide 3 -Tekstslide

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?

#### Slide 4 -Tekstslide

Angle pairs on parallel lines
3. Name an angle pair which is co-interior.

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

#### Slide 5 -Tekstslide

Angle pairs on parallel lines
4. Which other angle pairs do you know?

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

#### Slide 6 -Tekstslide

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

#### Slide 7 -Tekstslide

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)

#### Slide 8 -Tekstslide

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!

#### Slide 9 -Tekstslide

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
