Do you remember what the word parallel means? Write down the definition for it:

_____________________________________________________________________

_____________________________________________________________________

Let's begin with some "puzzles"!

Look at the sketches below and answer the questions that follow:

1. Indicate whether EF and GH are parallel to one another in figure

A: __________________________________________________________________

B: __________________________________________________________________

2. Which is the extension of F: C or K?

Do you still remember?

indicates a line: AB
indicates a line segment: EF
indicates a radius: CD

Two lines that intersect form an angle.

The point where the lines meet is called the vertex.

We write this as: ÐABC

  • Did you know?

The unit that we use for measuring angles is a degree. We measure

the size of the angle in degrees. We write an angle of 60 degrees as 60°.

You have to learn the different types of angles:

Types of angles
1. The size of a rotation or full turn is 360°
2. A straight angle is a half turn and it is 180°.
3. A right angle is a quarter turn and it is 90°.
4. An acute angle is larger that 0°, but smaller than 90°.
5. An obtuse angle is larger than 90°, but smaller than 180°.

Activity: recognising and describing angles [lo 4.11]

1. How well do you know angles?

Work with a partner to see if the two of you can tell what the following angles are:

1.1

1.2

1.3

1.4

Assessment

Learning Outcome 4: The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.

Assessment Standard 4.11: We know this when the learner recognises and describes angles in two-dimensional shapes, three-dimensional objects and the environment.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.

yes that's correct

industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
