Question

Determine how many lines of symmetry each object has. Then determine whether each object has rotational symmetry.

Answer 1

Answer:

The answer is A,

Step-by-step explanation:

Look for the key words

"Lines of Symmetry" which means that if it is cut or folded in half both sides would line up perfectly.

and the other key word

"Rotational Symmetry" which means the object does not change regardless of  how many times you rotate it.

Answer 2

The correct answer is: A: 2; yes

Step-by-step explanation:

Given object is a rectangle with some lines in it.

First of all lets define the line of symmetry and rotational symmetry.

Line of Symmetry:

Line of symmetry is a line on which if the figure is fold the figure is divided into two equal halves.

Rotational Symmetry:

Rotational symmetry means if the figure comes in its original form when rotated about its center point.

As we can see in the diagram, the circle inside the rectangle and the lines are symmetrical which means that if the figure is folded vertically or horizontally along imaginary lines the two halves will completely overlap.

So there will be two lines of symmetry.

Similarly, when the figure will be rotated along its center which is located inside the center, the figure will come twice along with it's original shape during its rotation

So,

The correct answer is: A: 2; yes
