Investigation
Homestudy


Math’s Mate due Tuesday
3.1 on p. 28 You may use key to help find areas of tilted squares. Otherwise, use strategy reviewed in class today (inscribing a tilted square in an upright square, finding negative space, continued. All computing is to be shown.

Make-up tests were given to some students
Went over check-up “test”-you will need this info for tonight’s homework as well
***save this to help you study for your unit test!

Note the areas you need to work on and come on Thursday for extra help in homework club. Ask Marc for assistance

To find the length of a tilted line segment, make a square that will go outside the square. Use slope to make the right lines.
step 2 Trace a square around the tilted square you have made.
step 3 Make a rectangle to turn one of the line segments into a triangle.
step 4 Find the area and divide by 2. This gives you the area of the negative space.
step 5 Find the area of the larger square and subtract the area of the negative space from this number.
step 6 The answer to the problem is the square root of your answer from step 5.

Investigation 3
page 27 hypotenuse- the longest side of a right triangle
conjecture-similar to a hypothesis. They are the opinions given after an analysis of the data has been completed.

You need your key to complete this.
***for each triangle, you will draw 3 adjacent squares like those shown on page 27
