Identifying Scale Factors in Geometry

What is the purpose of determining a scale factor between two figures?

• To understand if one figure is larger than the other

• To confirm if one figure is a scaled copy of the other

• To calculate the perimeter of the figures

• To find out which figure is newer

What method is used to determine the scale factor between two geometric figures?

• Dividing the length of a side in one figure by the corresponding side in the other

• Measuring the angles between corresponding sides

• Subtracting the lengths of corresponding sides

• Adding the lengths of all sides

How can we verify that Figure B is a scaled copy of Figure A?

• By measuring the area of both figures

• By comparing the color of the figures

• By checking if all corresponding sides have been scaled by the same factor

• By counting the number of sides

What does a scale factor of 3 indicate about the relationship between two figures?

• Figure B is three times smaller than Figure A

• Figure B is three times larger than Figure A

• Each side of Figure B is three times longer than the corresponding side in Figure A

• The figures are of the same size

Which statement confirms that Figure B is a scaled copy of Figure A?

• Only one side in Figure B matches a side in Figure A when scaled

• All corresponding sides in Figure B are three times the length of those in Figure A

• Figure B has more sides than Figure A
