**5.**A right triangle has side lengths of

**40mm**,

**75mm**, and

**85mm**.

**a)**Sketch the triangle. Draw a square on each side of the triangle.

**b)**What are the areas of the three squares?

The area for

**square a**, is**1,600mm2 (squared)**.The area for

**square b**, is**5,625mm2 (squared)**.The area for

**square c**, is**7,225mm2 (squared)**.

**c)**Write an addition statement with the areas of the three squares.

a(squared)+b(squared)=c(squared)

40(squared)+75(squared)=85(squared)

1,600(squared)+5,625(squared)=7,225(squared)

**7,225mm(squared)=7,225mm(squared)**

**10.**A triangle has side lengths of

**120mm**,

**160mm**, and

**200mm**. Is the triangle a

*? Explain your reasoning.*

**right triangle**

*Yes*, this is a right triangle because the sum of the area of each leg, is

**to the area of the hypotenuse.**

*equal*a(squared)+b(squared)=c(squared)

120(squared)+160(squared)=200(squared)

14,400(squared)+25,600(squared)=40,000(squared)

**40,000(squared)=40,000(squared)**

**15.**Construction workers have begun to dig a hole for a swimming pool. They want to check that the angle they have dug is

*90 degrees*. They measure the diagonal as shown to be

**9.5m**. Is the angle 90 degrees? Explain your reasoning.

*No*, the angle is not 90 degrees because the sum of the area of each leg, is

**to the area of the hypotenuse.**

*not equal*

**19.**A

*right triangle*has a square attached to each side. Two of the squares have areas of

**10cm(squared)**and

**15cm(squared)**. What are the possible areas for the third square? Draw a sketch for each solution.

There is

**only one possible area**for the third square, and that is the sum of the area of each leg:**25cm(squared)**. There is only one possible area because it is a**.***right triangle*
I don't know why the words are all squished together. I made sure that I spaced them out, but it turned out all bunched up..

ReplyDeleteWhen I edit the post and space out the words, they still end up being squished..

ReplyDeleteGood job Ryan, Dont worry , I have the same problem. I like your pictures and I like how you used the same colours. All in all great job. keep it up ..

ReplyDeleteGood job Ryan! That spacing problem happened to me before too. I like the colours you used, and I like your pictures, they were clear and neat. I got the same answers as you. Good job, keep it up!(:

ReplyDeleteNice job Ryan! It's still good, I also had it but I saw the problem on the preview though so i double spaced it and for me it worked. I liked how you used different colors on important words and your pictures are so clear. Keep it up!

ReplyDeleteGreat job, Ryan :D

ReplyDeleteAlthough your words are all bunched up, your post was really well done ! I really liked the pictures, and how you changed the colors. Keep it up !
