**Do you see any acute, right, or obtuse angles in your house?**

**Tell us about them!**

Dear Mrs. Ranney and class,

ReplyDeleteI am Mrs. Yollis' student, Aashi. In class, we have been learning about angles too.

I think

obtuseandacuteare much better vocabulary thangreater than a right angleandless than a right angle.Another name for a right angle is a 90 degree angle. In class, we are using the lofty vocabulary words obtuse, acute, right angle, or 90 degree to enhance our vocabulary skills.I see a 90 degree angle on the American flag, a piece of paper, on a face of a microwave, the

publishandpreviewbuttons on your blog, Mrs. Yollis' blog, and some other blogs, the screen of my TV, and a capital L.I would see an acute angle on a slice of cheese pizza and any kind of V. I find obtuse angles on a analog clock when it strikes 6:00, an open book's edges, and a reclined driver's seat.

What other letters have a right angle (90 degree), obtuse angle, or an acute angle?

Sincerely,

Aashi

Dear Mrs. Ranny and class,

ReplyDeleteI see many right angle(90˚), acutes, and, obtuse in my house. There are many 90˚angles around you, even the computer I am using has 4 90˚angles

Aashi, I agree with you 90˚angle, acutes, and, obtuse are a more accurate vocabulary. You used a lot of them, and I will try to get some in. I see a 90˚angle on the corners of a light switch, some tables corners, doors, and usually cabinets have them. For acute I have <>brackets, triangles, and an ice cream cone. Its not prefect, but a U. I am having a hard time thinking of a obtuse.

Whats your favorite 90˚, obtuse, or acute?

Sincerely,

Daniel (from Mrs. Yollis's class)

Dear Class,

ReplyDeleteIn my house, I noticed some objects that have angles:

One example is the corner of my kitchen counter. It is a right angle. Another one is when I open my fridge, it makes an obtuse angle. Here is another one, when I lift a basket (that holds our bread), it makes a small acute angle. Next, is a microwave. It has a right angle and when you open it, it has another right angle. Isn't that awesome!

What objects can you find around the house?

Your classmate,

Jacob

Dear Class,

ReplyDeleteI

foundobjects that have right, obtuse or acute angles.For example, I

sawthe time, whichwas5:19 PM. The angle between the hour hand and the minute hand is an acute angle.The wii machine has an obtuse angle. My picture frame has 4 right angles.

I noticed that I

foundmany things that have right angles in my house.My favorite angle is acute angle.

How is your favorite angle?

Cheers,
