4.  The purpose of this study guide is to teach the definition of an angle and types of angles

5.  You will HAVE TO complete two sections. Beginning with the definition of an angle, followed by types of angles: ◦ What is an angle? ◦ Types of angles

6. What is ‘an angle’?Types of Angles

7. Sorry, you can not choose this section! Go back!

8. An angle: A shape formed by two rays sharing a common endpoint; contains two rays and a vertex. Please choose the button to get more information about rays and a vertex! A B C Vertex Ray

9. Vertex - point common to two rays of a triangle or two sides of polygon! Vertex

10. An angle: A shape formed by two rays sharing a common endpoint; contains two rays and a vertex. Please choose the button to get more information about rays and a vertex! A B C Vertex Ray

11. Ray - has one endpoint and goes infinitely in one direction Ray

12.  If we look around us, we can see angles everywhere! Where can you see angles around you? Angles

13. Now, you will answer questions about the information you learned. Click the button under the clock to go to QUIZ page!!

14. Find the name of the part of this angle. Click the right button. This is the ? Vertex Ray

15. The answer is VERTEX Now, try the next question!

34.  One angle measures greater than 90 degrees and less than 180 degrees

36.  Click the cloud to learn the type of the angle! Right Angle Obtuse Angle Straight Angle Acute Angle

37.  A line that goes infinitely in both directions and measures 180 degrees

39. Now, you will answer questions about the information you learned. Click the button under the clock to go to QUIZ page!!

40. Which angle is a right angle? Click the arrow to find the right angle. 1 2 3 4 5

41. Now, try the next question! 1 2 3 4 5

42. That was not right. TRY again!!!

43. Which angle is an obtuse angle? Click the arrow to find the obtuse angle. 1 2 3 4 5

44. Now, try the next question! 1 2 3 4 5

45. That was not right. TRY again!!!

46. Which angles are not acute? Click the arrow to find the answer! 1 2 3 4 5

47. 2 is not an acute angle, it is a right angle 5 is not an acute angle, it is an obtuse angle Now, try the next question! 1 2 3 4 5

48. That was not right. 1,3,4 are acute angles. TRY again!!!

49. Which is a straight angle? Click one of the arrows to find the answer.

50. Now, you complete the test. Click the next button.

51. That was not right. This is a ray. It only goes in one direction. TRY again!!!
