### 17-18 Geometry Daily Log

#### Special right triangles 1/16

Today we practiced applying the shortcuts to the Pythagorean theorem and looked at applying them to triangles graphed on a grid. Here is a helpful website for special right triangles. http://www.mathwarehouse.com/geometry/triangles/right-triangles/special-right-triangles.php Triangles on a grid worksheet: |

#### Special right triangles 1/12

Today we kept working on finding patterns to the Pythagorean theorem and practicing applying them. |

#### PSAT practice test 1/10

The information about the test is here. If you missed class, you will need to do the practice test on your own. A copy of the complete PSAT practice test is linked below. You can print the bubble sheet or just write your answer on a piece of paper. You only need to do sections 4. Section calculator allowed, 45 minutes. The reflection in the google slides is required for a classwork grade. Practice PSAT test |

#### Simplifying radicals and special right triangles 1/9

We finished the mentor text memory challenge today and everyone received a yellow copy of the mentor text with some additional examples on the back for reference. Today's presentation |

#### Side length properties of triangles 10/9

Today we looked at side length properties of triangles. Triangle inequality theorem We used Geogebra to explore patterns of side lengths using the converse to the Pythagorean theorem. We will continue with the investigation tomorrow. Homework: Khan assignments due the end of the week (end of the day Thursday since you have Friday off.) |

#### Angle properties in triangles 10/6

Today we looked at the triangle sum theorem and the exterior angle theorem. Here are a couple videos to help see what they are. Then we completed the attached puzzle using classification and angle properties we've been working on. |

#### Stations 10/4

First, we looked up grades since 6 week grades are posting this week. Then we split into three groups for rotations: Ms. Miller and Mrs. Maseberg- work on project Mrs. Stewart- online Geometric proofs Mr. Sundbye- triangle sum theorem |
