A Video to Review Trigonometric Equations

The bellwork question is ... how tall is Optimus Prime, if his 'line of sight' to Sam Witwicky is 96 feet, the angle of elevation from Sam is 50.8 degrees, after battling Sentinel and Megatron?

Chapter 6: Parallelograms

There are many quadrilaterals to talk about. Last week, we mentioned parallelograms, kites, and rhombi. Here is a video to watch.



After watching the video, for extra credit due on Monday (separate sheet of paper) answer the following questions:

1) What was one of the properties mentioned in the video but not in the class?
2) What is another word that stands for consecutive that we talked about in class, referring to property four in the video?

Question unrelated to the video: 3) What is the distance formula?

This week, we will talk about parallelograms and their properties more and rhombi.

Spring Break, Enjoy! Class starts back on April 14th. The Big Push Is On!

Next week, we will be covering several topics: 1) special right triangles, 2) ratio trigonometry, and 3) angle of elevation and depression. If you can understand the first two concepts, the third concept is easy to do.

Here two videos about the two types of special right triangles:







For extra credit, rewatch the videos and answer the following questions and turn them in on a sheet of paper Monday!
1) From the first video, if x = 11, what is the value of the hypotenuse in a 45-90-45 triangle?
2) From the second video, if x = 1.5, what are the values of all three sides in a 30-60-90 triangle?
3) From the third video, if a = 21, b = 28, and c = 35 what are the trigonometric ratios from a non right angle?
