Discuss about manything of Angles

Well this topics is about angles and we discuss actually in long time ago but we have already to finish yet today.

We discuss about it almoust every day because it easy enough and actually we practice to discuss is for about increase our vocabularry and grammar that suppose to be basic to become great in english. and the under of this paragraph is the result,

Discuss about Angles

Place : In Mahendra's Homestay
Date : Monday 12 th on January
Time : 13.00 - 18.00 pm

Agung: Today we are going to learn about angles. So what do you know about angles??

Ali: I know what an angle is! It is two rays connected together
Agung: That is correct!! how did you know??Did you read that from your book?
Ali:Yes. on basic concept geometry
Agung:

Well, there are three categories of angles: acute, obtuse and right.. Right angles are present many places in real life. Look at the corners of this room or the edges of your books. A right angle is an angle that measures 90 degrees.

The second type of angle is acute. An acute angle is an angle whose measure is less than 90 degrees.

Ali: Let me guess! The third type is an angle whose measure is more than 90 degrees. am i right??

Agung:
Yes, and the name of that angle is obtuse.We also have names for pairs of angles. Angles are formed when lines intersect. We are going to look at the angles formed when two parallel lines are intersected by a third line called a transversal . In this picture we can see what i mean










Ali: Those lines formed 8 angles?? am i right again agung??
Agung: . . . . .

Agung: Good job. Now, who can show me an acute angle?
Ali: can! It is the one on the top right, and illustrate with b and f
Agung: Right again. But, can you show me an obtuse angle?
Ali: yes of course. . .and the answers is a and e

Agung:
Correct. We need an easier way of referring to the angles we are talking about. So from now on, we will label our angles. Angles a and b are adjacent angles
Angles f and h are also adjacent angles. did you know what it means for a pair of angles to be adjacent? Does it mean that they are side by side? what about your answers??

Ali: Mmmm I'm follow with you

Agung: yes, adjacent angles are angles that share a ray, Can you tell me another pair of angles that are adjacent?
Ali: angles c and d and angles b and d ?
Agung: That is correct
Ali: Thanks friend

Agung:

There are many pairs of adjacent angles in the picture. Now, let's talk about vertical angle. Angles a and d are vertical angles. Angles f and g are also vertical angles.


Ali: Are vertical angles ones that are opposite from each other?
Agung:

Vertical angles share only one point. That point is called the vertex angles b and c are vertical angles and so are angles e and h. Now that we know what adjacent and vertical angles are,
Agung: I think it's enough, thank you for giving me a separe time that we can use for discuss about it.
Ali: you're welcome agung, and thanks for share about your knowledge.With that i can learn about english more happily. Thanks
