Amy draws a circle. she shades 1/360 of the circle. How many degrees did she shade? What is the name of this angle?

Question

2nd question: Find 10 angles in a room. Sketch each angle and classify it as right angle,less than a right angle, or greater than a right angle?

Answer 1

Hi Karen--

 

Since a circle measures 360 degrees, 1/360 of it would be one degree, a very "skinny" angle, which, since it is less than 90 degrees, is called an Acute angle.

 

The second question you'll need to do a little hunting around your home. Look for angles where walls meet each other, or wall-to-floor, etc. You can also sketch or even measure the angles of things like open doors, the angle of the side of a pot or pan sitting on the counter, a spoon leaning against the inside of a coffee cup, etc.

 

If the angle looks like the letter L (forwards, backwards, upside down, any position) it's a right (90 degree) angle.

 

If its "arms" (rays) are more open than a right angle (more than 90 degrees) it's called an Obtuse angle. If the arms are more closed (less than 90) it's an Acute angle.

 

Hope this helps!
