HW: Quiz 10.4 - 10.5 is Monday, the 10.4/10.5 packet should be done and turned in.
Students were given a short entrance slip which they had a couple of minutes to complete. We went over this in class. Students completed an 8 question review finding the missing side of a right triangle using trig ratios.
HW: Quiz 10.4 - 10.5 is Monday, the 10.4/10.5 packet should be done and turned in. Using the boards in the room, students worked were able find the missing side of a given right triangle knowing an angle and a side.

We completed our examples using the trig ratios to find the missing side of a right triangle. Then we listened to the Gettin' Triggy With It video. The link is below.

We complete the day 1 notes on trig ratios.

We went over the sheet. This is a good study guide for the short c
We completed the first page of today's notes on trigonometric ratios. HW: Be ready for tomorrow's summative assessment (test) tomorrow on special triangles (STD 11) We played 2 Kahoot review games where students were asked to find the missing side of a special right triangle (45-45-90 or 30-60-90). Then students had about 15 minutes to complete today's review worksheet of 10.2- 10.3.
HW: Complete today's WS and turn in your 10.2 and 10.3 packets We started by completing an 8 question review of 45 - 45 - 90 triangles using Kahoot. We went over the day 1 10.3 assignment. Then students had the rest of class to complete day attached day 2 assignment.
HW: complete day attached day 2 10.3 assignment Today we looked at a second special triangle, called a 30-60-90 triangle. This is a right scalene where the hypotenuse = 2* short leg (shorty) and the longer leg = short leg*square root 3. We completed all our class notes and students were given a short flash card quiz over 45-45-90 triangles.

They were asked to find the missing sides. We also went over the day 1 assignment from yesterday and quickly completed the last 4 problems for our notes today. Students had about 20 - 25 minutes to complete the day 2 homework assignment.
HW: Complete the attached WS Day 2 assignment Students were given a (square) piece of paper and measure the consecutive sides to confirm it was a square. Then they folded it corner to corner to create a right isosceles triangle. We measured the length of the hypotenuse and also calculated it by using the Pythagorean theorem. Then we looked at the ratio of the hypotenuse to the leg and found it was about 1.41. We used GeoGebra to examine more 45-45-90 triangles and calculated the ratio of the hypotenuse to the leg and again found it was about 1.41. We looked at the general case of a right isosceles triangle and by using the Pythagorean theorem, we saw that the hypotenuse = leg*square root of 2. We completed our notes on section 10.2.
