  2. Greeting space cadet! I am Captain Stargaze. Today I have a very important mission for you. Princess Twilight has been captured by the Knight of Polygon, and I need your help to rescue her! Click on the planet to see what your mission is!

  3. The planet of Polygon is divided into several different countries. Princess Twilight is being held captive in Triangular, a land of triangles. What is a triangle you ask? Click on the star to find out…

  4. Triangle A triangle is one of the basic shapes of geometry: a polygon with three corners and three sides which are straight line segments. • Next

  5. A triangle has three angles. The sum of these three angles always equals 180°. • Next

  6. Mission: Your mission is to research and learn about triangles to prepare to rescue Princess Twilight. Pay careful attention to the way that triangles are classified! If you chose to accept this mission, you must board the space ship by Clicking on it….

  7. There are two different ways to classify triangles: • By the lengths of their sides. • And by the size of their angles. Click on the triangle to continue

  8. You recently learned about the different types of angles. Obtuse angle Acute angle Right angle Straight angle • Next

  9. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle

  10. Right Triangles Right triangles are triangles that have a right angle (90°). 90° angle Continue

  11. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle

  12. Acute Triangles Acute triangles are triangles that have angles less than 90°. Less than 90° Continue

  13. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle Obtuse Triangle

  14. Obtuse Angles An obtuse triangle is a triangle that has one obtuse angle (an angle greater than 90°). Greater than 90° Continue

  15. Now let’s review… Click on the BIG star to continue.

  16. An obtuse triangle is a triangle that has one angle that is… Less than 90° Equals 90° Greater than 90° Equals 180°

  17. GREAT JOB! That is correct!! An obtuse triangle has an angle that is GREATER than 90°. Continue

  18. Not Quite!! Let’s try that one again… Remember…what does the word “obtuse” mean? Click on the triangle to try again.

  19. Triangles can be classified by the lengths of their sides and…. The size of their angles The shape that the make The amount of angles they have The color of the triangle

  20. GREAT JOB! That is correct!! Triangles are classified by the lengths of their sides as well as the size of their angles. Continue

  21. That is Incorrect!! Maybe we should take another look at this…. Click on the face above to continue.

  22. There are two different ways to classify triangles: • By the lengths of their sides. • And by the size of their angles. Click on the triangle to continue

  23. You recently learned about the different types of angles. Obtuse angle Acute angle Right angle Straight angle • Next

  24. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle

  25. Right Triangles Right triangles are triangles that have a right angle (90°). 90° angle Continue

  26. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle

  27. Acute Triangles Acute triangles are triangles that have angles less than 90°. Less than 90° Continue

  28. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle Obtuse Triangle

  29. Obtuse Angles An obtuse triangle is a triangle that has one obtuse angle (an angle greater than 90°). 180° Continue

  30. There are three different types of triangles that are classified by the size of angles: Acute, obtuse, and … Isosceles triangle Straight triangle 90° triangle Right triangle

  31. CORRECT!! Wow! You really know your stuff! Click on the yellow star to continue!

  32. Oh Dear! Maybe we should take another look at this…. Click on the face above to continue.

  33. There are two different ways to classify triangles: • By the lengths of their sides. • And by the size of their angles. Click on the triangle to continue

  34. You recently learned about the different types of angles. Obtuse angle Acute angle Right angle Straight angle • Next

  35. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle

  36. Right Triangles Right triangles are triangles that have a right angle (90°). 90° angle Continue

  37. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle

  38. Acute Triangles Acute triangles are triangles that have angles less than 90°. Less than 90° Continue

  39. These types of angles are also used to classify triangles. Click on each to learn more. Right Triangle Acute Triangle Obtuse Triangle

  40. Obtuse Angles An obtuse triangle is a triangle that has one obtuse angle (an angle greater than 90°). Greater than 90° Continue

  41. Alright, you are doing a great job so far! Let’s continue on…. Click on the star to continue.

  42. You can also classify triangles by the length of their sides. There are three different types of triangles. Click on each to learn more. 1. Isosceles 3. Scalene 2. Equilateral

  43. Isosceles Triangles An Isosceles triangle is a triangle that has TWO sides that are the same length. Click on star to continue

  44. You can also classify triangles by the length of their sides. There are three different types of triangles.Click on each to learn more. 1. Isosceles 3. Scalene 2. Equilateral

  45. Equilateral Triangles An Equilateral triangle is a triangle that has three equal sides. This means that all of the sides have the same length. NEXT

  46. Equilateral triangles not only have three equal sides, but they have three angles that are equal as well. The angles of an equilateral triangle equal 60° each. If you add all three angles together, it equals 180°. NEXT

  47. You can also classify triangles by the length of their sides. There are three different types of triangles.Click on each to learn more. 1. Isosceles 3. Scalene 2. Equilateral

  48. Scalene Triangles A scalene triangle is a triangle that has three sides with different lengths. NEXT

  49. Greetings Earthling! This is your FIRST challenge in rescuing the princess. Think hard about your answer! Click on the creature above to continue.

  50. Select the isosceles triangle… Remember: An isosceles triangle is a triangle with two equal sides.
