To solve this, we need to compare each angle to a right angle.
What is a right angle?
A right angle is exactly 90 degrees. It looks like the corner of a square or a book. It forms a perfect "L" shape.
How to tell if an angle is less or more:
*
Less than: If the angle is smaller/narrower than a perfect "L", it is less than a right angle.
*
More than: If the angle is wider/opened up more than a perfect "L", it is more than a right angle.
Let's look at each angle in the worksheet:
1.
Top Left: This angle is very narrow and pointy. It is much smaller than an "L". ->
less than
2.
Top Middle: This angle is wide open. It is bigger than an "L". ->
more than
3.
Top Right: This angle is very narrow and pointy. It is smaller than an "L". ->
less than
4.
Middle Left: This angle is wide open. It is bigger than an "L". ->
more than
5.
Middle Center: This angle is sharp and narrow. It is smaller than an "L". ->
less than
6.
Middle Right: This angle is somewhat wide, but let's look closely. The bottom line is horizontal. The other line goes up and right. A right angle would go straight up. Since this line leans to the right, the opening is smaller than 90 degrees. ->
less than
7.
Bottom Left: This looks like the top of a triangle. Both sides slope inward. This makes the angle at the top smaller than a square corner. ->
less than
8.
Bottom Right: This angle is wide open. The lines are spread apart more than an "L". ->
more than
Final Answer:
* Top Left:
less than
* Top Middle:
more than
* Top Right:
less than
* Middle Left:
more than
* Middle Center:
less than
* Middle Right:
less than
* Bottom Left:
less than
* Bottom Right:
more than
