1.

a) Yes

b) Yes

c) Yes

## Activity: revising [lo 3.3, lo 3.7]

1. Why don’t we start by revising a bit? Get your thinking caps on!

a) Are KL and MN parallel?

b) Is OP equidistant from QR?

c) Are the following three line segments equally spaced from each other?

1.4 Use the dots as corners and draw an equilateral triangle, a square and a rectangle.

1.5 Join the dots together so that you will form a parallelogram and a rhombus.

1.6 Use the dots as corners and draw:

a) two triangles of the same shape and size

b) an equilateral triangle

c) a right-angled triangle

(You must use all the dots and you may use each dot only once).

1.7 Draw in all the diagonals of this regular pentagon. Then colour in the only polygon that has been formed.

2. See if you can draw the following (use your protractor and ruler):

2.1 Draw a pentagon where each side is 50 mm long and each corner angle is 108 degrees.

2.2 Draw an octagon where each side is 40 mm long and each corner angle is 135 degrees.

## Assessment

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 uses a pair of compasses, ruler and protractor to accurately construct geometric figures for investigation of own property and design of nets.

Assessment Standard 3.7: We know this when the learner draws and interprets sketches of solids from different perspectives.

What is significance of vector?
what is impulse?
the product of force and time
Robert
find the flow rate of a fluid of viscosity 0.0015N-s/m³ flowing through a pipe of radius 50cm and length 100m at a pressure differential of 200000N/m²
friend ,what is the equation your question
lasitha
What is victor
How are you all?
what is the formula for momentum?
p=mv
Grant
what is the formula for angular displacement ?
lasitha
angular displacement = l/r
anand
friend ,what is the " l "?
lasitha
I have another problem,what is the difference between pure chemistry and applied chemistry ?
lasitha
l stands for linear displacement and l>>r
anand
r stands for radius or position vector of particle
anand
pure chemistry is related to classical and basic concepts of chemistry while applied Chemistry deals with it's application oriented concepts and procedures.
anand
what is the deference between precision and accuracy?
ShAmy
I think in general both are same , more accuracy means more precise
anand
and lessor error
anand
friends,how to find correct applied chemistry notes?
lasitha
what are the main concepts of applied chemistry ?
lasitha
anand,can you give an example for angular displacement ?
lasitha
when any particle rotates or revolves about something , an axis or point ,then angle traversed is angular displacement
anand
like a revolving fan
anand
yeah ,I understood now, thanks!
lasitha
o need this application in French language
Why is it that the definition is not there
Bello
what is physics
the study of matter in relation to energy
Robert
Ampher law
Zia
how do convert acceleration
multiply by 3.6

how did John Dalton contribute to A.theory?
Angela
Atomic theory,
Angela
according to John Dalton all the matter was composed of atom and indivisible, indestructible building blocks. while the atom of different elements have different mass and size.

two parallel wires are 5.80cm apart and carry currents in opposite direction , as shown in figure .find the magnitude and direction of the magnetic field at point p due to two 1.50mm segments of wire that are opposite each other and each 8.00 cm from p.
solve it
Barilee

Harish
total heat of substance known as
total substance known as?
Twinkle
mole
Robert
what is reference?
what is avector
pretty much just a line with an arrow that represents the magnitude and direction of a quantity.
Shii
vector is quantity, that has magnitude and direction
