Example Questions
Example Question #42 : Geometry
If I cut a circle in half, how am I changing the size?
Each piece will be different sizes.
Each piece will be bigger than the circle
Each pieces will be smaller than the circle, they will be half the size.
Each piece will be the same size as the circle.
Each pieces will be smaller than the circle, they will be half the size.
When we cut something in half, we get two smaller pieces that equal each other. If we put those pieces back together, we’d get the original size of the circle.
Example Question #43 : Geometry
If we have two circles of the same size, and we cut one of them in half, and one of them in fourths, which pieces will be smaller?
The circle that we cut in half.
They will both have pieces of the same size.
The circle that we cut into fourths.
They will both have pieces of bigger sizes than the original circle.
The circle that we cut into fourths.
Cutting an object into four pieces makes the pieces smaller because a fourth is smaller than a half.
Example Question #47 : Geometry
What portion of the circle is green?
A half
A fourth
A quater
A third
A half
The circle is split into two pieces and one of those pieces is colored green. This means that half of the circle is green.
Example Question #41 : Geometry
What portion of the circle is green?
A fifth
A half
A fourth
A third
A fourth
The circle is split into four pieces and one of those pieces is colored green. This means that a fourth of the circle is green.
