Activity: to investigate and compare 2-dimensional figures [lo 3.3.3]

Looking at circles:

1. Have a good look at the sketch and then answer the questions:

RQ = Diameter

SP = Radius

1.1 What is a circle?


1.2 Where do we come across circles in our daily lives?



2. Answer the following questions:

2.1 How many diameters could a circle have? _____________________________

2.2 How many centre points could a circle have? __________________________

2.3 How many radii could a circle have? ________________________________

3. Use a pair of compasses and draw a circle with a:

3.1 radius of 30 mm:

3.2 diameter of 80 mm:


We can draw lovely patterns based on circles! The pattern shown

below is known as a paisley design and is used on cloth or clothing.

4. Can you find out how the pattern is created? Try to do it yourself!

5. Follow the steps and use this method for drawing the patterns that follow. Your educator will provide the paper that you need.

Draw a circle Use the same radius for marking the circumference Connect the points (if necessary)

Draw a circle

Use the same radius for marking the circumference

Connect the points (if necessary)





6. Design your own pattern with circles. Colour it neatly:

Time for self-assessment

It is important to know how well you understand the work that we have done up to now. Read the following criteria. Evaluate yourself on a scale ranging from 1 to 4 by circling the appropriate number.

Criteria 1 = Not at all.2 = Just a little.3 = Well.4 = Very well.
I can explain the term "parallel". 1 2 3 4
I can explain the difference between a line and a line segment. 1 2 3 4
I can explain the following concepts:
* acute angle; 1 2 3 4
* obtuse angle; 1 2 3 4
* right angle. 1 2 3 4
I can use a protractor to:
* measure angles accurately; 1 2 3 4
* draw angles accurately. 1 2 3 4
I can name the similarities between a rectangle and a parallelogram 1 2 3 4
I can name the differences between a rectangle and a parallelogram. 1 2 3 4
I can explain the concept "symmetrical". 1 2 3 4
I can explain the concept "rotational symmetry". 1 2 3 4
I can explain the following concepts:
* radius; 1 2 3 4
* diameter. 1 2 3 4
I could enlarge and reduce the figures. 1 2 3 4
I can use circles to draw patterns. 1 2 3 4

Let's look at 3-dimensional figures.

You probably quite often play games that require a die. See if you can make one yourself. Trace the outlines of the following net exactly. Cut it out neatly and fold it to form a die. Then write the numbers 1 to 6 on the sides. Remember that the numbers of the following number pairs (1,6), (3,4) and (2,5) must be on opposite sides.


The die that you have just made is an example of a cube.

Take a good look at the following:


Learning Outcome 3: The learner will be able to describe and represent characteristics and relationships between two-dimensional shapes and three-dimensional objects in a variety of orientations and positions.

Assessment Standard 3.3: We know this when the learner investigates and compares (alone or as a member of a group or team) two-dimensional shapes and three-dimensional objects studied in this grade according to properties listed above by:

3.3.3: using a pair of compasses to draw circles, patterns in circles, and patterns with circles.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log

Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
I'm interested in nanotube
what is nanomaterials​ and their applications of sensors.

what is system testing?
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
