### Angles

Angles
The space between two connecting lines.

Acute
An angle that is less than 90°.
Obtuse
An angle that is greater then 90° and less than 180°

Right
An angle that is exactly 90°
Straight
An angle that is exactly 180°

Angle Bisector
The line that divides an angle into equal parts.
(equal angles are marked with the same mark)
Their are 3 ways to make an angle bisector.

1.a) Fold Paper until the 2 lines on your angle meet.
b) Use a ruler to draw a line on a crease.

2.a)Use a compass to make an arc from the vertex that crosses both arms. Label them x and y
b)Make an arc from point x and point y. They must be equal in size.
c) Draw a line from point B to the between the meter section.
3.a)Use a protractor.
(angle)
b)Measure the < D E F.

140°

c)Divide your measurement by 2. 140÷2= 70°.

d)Make a mark at 70° using a protractor. Label it Q.

e)Join point Q with the vertex with a straight line.
1. Make a 68° angle. Then draw the angle bisector using 2 methods.
2.How could you divide an angle into 4 equal parts ?
You can find out the angle and then divide it by 4.
3.Has each angle been bisected? How do you know ?

No because A is cut in half and B isn't cut into equal parts.

4.What are 2 examples of angle bisectors in the real world?
Pizza
and Pie.

1. Great post Patrick, I really like the pictures, they made things a lot easier to understand. Maybe try to use less colors much to flashy and I swear my eyes kind of hurt just looking at all those colors, and it would be great if you added a video too.

2. Good job Patrick! It was very good. But you should have added a video.

3. Great job, Patrick! The pictures made it easier to understand about the angles, but next time try to add a video! Overall, good job on the scribe post!

4. Good job Patrick! I really like you post. Next time try adding a video. Overall, it was impressive.

5. Great job Patrick! I like how you drew some of the pictures yourself, Next time maybe find a video, but besides that Good job!

6. Great post Patrick!! I liked how you put in more than one picture, it made the definitions easier to understand. But I think all of the colors were kind of confusing to look at. Next time I would only make the important facts a different color. But overall nice post!

7. Nice post Patrick!!! I really liked how you had a picture for each of the ways to create an angle bisector. The ony thing I did't like was the fact that there was little picture symbols that blocked some of the words and I couldn't access the link because of teh picture symbols. Otherwise great work!!!!!!!

8. Good job patrick everything was great and easy to understand but next time don't put too much color on the fonts and add a video, but everything was great and neat. GREAT JOB!
