Did you look for the Think and Discuss online?  It should be there.  Then just post your answers here.

Mrs.Weaknecht, I didn't bring the book home and I don't know how to do the Think and Discuss online. Is there a way I can still do it?

1)An octagan has eight triangles that are congruent to each other . if you have the area of one triangle you can multiply it by  eight to get the area of the octogan.
2)You can break the trapezoid into three congruent triangles. find the area of each triangle then add.

1. The area of a triangle and the area of a rectangle that have the same base and the same height are related because the area of a triangle is half of its base times height and the area for a rectangle is length times width. The length times the width of a rectangle gives the same product as the base times the height, and a triangle that has the same base and height as a rectangle would be exactly half of the rectangle.

2. The formula for the area of a square is length times width.

1. You can find the area of regular octagon by breaking it apart into eight congruent triangles. If you know the area of one triangle, then you can multiply it by 8. This is because eight triangles are eight times one triangle.

2. One way you can find the area of a trapezoid is by breaking it apart into two triangles and a square. You would first multiply length times width to find the area of the square, then multiply 1/2 times base times height twice to find the areas of the two triangles. To find the total area of the trapezoid, add all the products together.

1.The relationship between the triangle and rectangle is that the base of the
triangle is half of the rectangles base
2.length or width times 4

1.find the area of the the 1st triangle and then multiply it by 8
2.make the trapezoid into two triangles and a rectangle or square and then add the areas of each polygon.

1)The formula for the area of a triangle is 1/2 of the base times the hight .
2)The formula for the area of a square is length times width.

10.3

1. You can break apart the regular octagon into 8 congruent triangles. Then, once you find the area of one triangle, multiply that by 8 (8 triangles in a regular octagon) to get the total area of the regular octagon.

2. One way to find the area of a trapezoid is by splitting it into rectangle and 2 triangles (shapes may vary depending on size). Find the area of the rectangle and  triangles. Add 'em all up, to get the area of a rectangle.

10.2

1. The area of a triangle and the area of a rectangle are related. This is because the area of a triangle is half the area of a rectangle. (A= 1/2 bh).

2. A=L^2 or W^2                                           (^2= squared)

10.2

1) The area of a triangle and the area of a rectangle are related because the formula to find the area of a triangle is V = 1/2bh. (1/2 times base times hight.)This means that the triangle's area is 1/2 of the rectangle's area.

2) A = L^2
A = W^2.                ( ^2 squared)

10.3

1) To find the area of a regular octagon be using triangles is yo have to multiply the area of one triangle by 8. To find the area of f a octagon you have to multiply the area on one triangle b 8 because there are 8 congruent triangles in a regular octagon.

2) One way to find the area of a trapezoid is to add the length of both the parallel lines and the divide by 2. Then you have La cara5 de la Unidad Materna, que casi siempre exhibe un aspecto cariñoso, ahora se transforma en la cara del enemigo6 Vulcan to multiply that by the height of the trapezoid.

Lesson 10.3

1. A regular octagon can be split into  8 congruent triangles. When the area of one triangle is found, you can multiply that by 8 to find the total area of the octagon.

2. You can split a trapezoid into 2 triangles and 1 square or rectangle ,depending on the size, and find the area separately. Once all the areas are found, they can be added to find the total area.

Lesson 10-3

1) To find the area of a regular octagon by breaking it apart into congruent triangles if you know the area of one triangle you must multiply the area of the triangle by 8. This is because, there are 8 congruent triangles that make up a regular octagon. So if you know the area of 1 triangle the area of the regular octagon will be 8 times that area.

2) One way you could find the area of a trapezoid that has no right angles is by dividing the trapezoid into 1 rectangle and 2 right triangles. Once the trapezoid is divided, then put the 2 right angles together to form a square. Once you form the square, then find the area of both the square and rectangle. After you find both areas add them together to find the area of the trapezoid.

Lesson 10-2

1) The area of a triangle and the area of a rectangle that have the same base and same height are related. I know this because the triangle's area is half of the rectangle's if the base and height are the same. This is because of the formula used for finding the area of a triangle. This is how I know that a triangle with the same base and height as a rectangle have related areas.

2) W^2 or L^2 ( ^2 means squared)

Lesson 10.2

1. The area of a triangle and the area of a rectangle that have the same base and height are related because the triangle is half of the area of the rectangle. I know this because if you were to find the area of the triangle and the rectangle, you would see that the triangle's area is half of the rectangle's area.
2. l^2 or w^2 (^2 is squared)

1.  Lesson 10.2 pg. 504-507 ....Read through and follow the formulas and step-by-step instructions (blue text) for finding or estimating area.  Please post your answers to the Think and Discuss questions (pg. 505) in a Padlet post here.  Please do Practice C for Lesson 10.2.  You may use either decimals or fractions.

2.  Lesson 10.3 pg. 508-510....  The general idea here is that we can beak apart irregular polygons into rectangles, parallelograms, and triangles in order to find their total area.  You'll need to be a good visual/spatial thinker to find the most efficient way to break the polygons apart.

Read through the examples for this lesson.  Please post your answers to the Think and Discuss questions (pg. 509) here.  Then do PROBLEM SOLVING for Lesson 10.3.  If you're looking for an extra challenge, do Practice C for Lesson 10.3.  It's a FUN one! ;)

If you want to...you may create ONE post including both lessons' responses.  If not, I'll be looking for two posts from you:  one for Lesson 10.2 and one for Lesson 10.3.

Any question?  Post them here.
Have a great weekend, everyone!  See you on Monday!
