Welcome ...
+ to this first Long distance Lesson
+ Thanks to the technical developements you can work on ...
+ by yourself, but also a bit together,
+ starting right now with this LessonUp!
Slide 1 - Diapositive
A: §8.2 Grouping data
B: §10.2 Altitude
An introduction for B follows now!
(Math A pupils, please follow this too.
It only takes a few slides and then I've got an introduction to your paragraph!)
Slide 2 - Diapositive
So the subject for today is: the ALTITUDE (=hoogtelijn).
Of course the Challenge path is your learning path!
Slide 3 - Diapositive
Slide 4 - Diapositive
Comment:
As you can see in the previous picture:
+ an altitude (=hoogtelijn) is used to measure the distance from a vertex to the opposite side
+ an altitude can be outside the triangle!
Slide 5 - Diapositive
As you see in the Solution of 12a, you need:
+ a pencil
+ a geo triangle (straight lines, angle of 40 degrees)
+ a pair of compasses
+ forgetting these things is impossible now, because you are at home!!
Slide 6 - Diapositive
Here you see the Solution of 14c.
Question: What Rules for Angles of Triangles are used here?
Answer this in the next slide!
Slide 7 - Diapositive
These rules for triangles are:
A
opposite angles are equal
B
the angles of a triangle are 180 degrees together
C
a straight angle is 180 degrees
D
a triangles always has an obtuse angle
Slide 8 - Quiz
Answer:
1st: the 3 angles together are 180 degrees
2nd: a straight angle is 180 degrees
3rd: opposite angles are equal
Slide 9 - Diapositive
Slide 10 - Diapositive
Homework time.
Good luck, doing §8.2!
(In Classroom or Study square.)
Slide 11 - Diapositive
Math A, §8.2 Grouping data
A few fine points!
+ first a bit of Theory, then
+ 2 questions
Slide 12 - Diapositive
Study this closely; you can also use book 3B, p.15.
Slide 13 - Diapositive
There is something tricky about 'intervals'!
That's why we go on a bit on it.
Question:
What are the midpoints of these classes?
Fill in in next slide!
Slide 14 - Diapositive
The midpoints of the classes are:
A
3 8 13 mm
B
2 8 12 mm
C
2 7 12 mm
D
2.5 7.5 12.5 mm
Slide 15 - Quiz
Answer: 2.5 7.5 12.5
Why?
The first class goes from 0 to 5 (5 not included),
so in fact from 0 to 4.999999......
Now it is clear that 2.5 is in the middle.
Slide 16 - Diapositive
Answer this question on the next slide!
(You might be surprised.)
Slide 17 - Diapositive
Number of tickets is ...
A
42
B
42.5
C
