### Honors Geometry; 3/19

Our study of circles today focused on minor arcs, major arcs, semicircles and central angles. We demonstrated how these terms are related and what each one of them refers to when looking at a circle diagram. We went through some central angle and arc calculations together as well before the students got started on their assignment.

### Geometry; 3/16

We spent some time reviewing some major topics from chapter 8 today: geometric means, similar triangles, pythagorean theorem, specials right triangles, and trig application problems. The students did one of each type as a group and then got feedback on their success. They then got started on the chapter 8 review sheet. The chapter 8 test is on Monday.

### Honors Geometry; 3/16

We continued our study of circles today by taking a look at the different types of tangent lines that are associated with circle drawings. We also went over how to use the property of tangent lines being perpendicular to the radii of circles in a variety of problem types. The students then got started on their assignment.

### Geometry; 3/15

We continued our work with trig application problems today by showing how to handle %grade problems and scenarios involving shadows. Both of these types of problems were demonstrated and practiced together before the students got started on their assignment.

### Honors Geometry; 3/15

The students got their tests back today and were able to go over any questions that they still had. We then got started on the study of our unit on circles. Today was largely an introduction to several of the vocabulary words associated with circles. The students were able to get familiar with these new terms through a variety of drawings before getting started on the assignment.

### Geometry; 3/14

Our topic today centered on how to work with trig application problems. We discussed how to use angles of depression and angles of elevation in today's lesson and how to draw diagrams involving them. We went over 2-3 examples together before the students got started on their assignment.
