GHSGT Practice Similar Figures and the Coordinate Plane – 8 questions
1. Study Figures I and II. Determine which transformation, if any, of Figure I is shown in Figure II. • A. Rotation • B. Reflection • C. Translation • D. No transformation Figure I Figure II
2. Enrico has a picture that measures 5 inches in height and 7 inches in length. If Enrico enlarges the picture so that the height is 15 inches, what is the length? • A. 7 in. • B. 10 in. • C. 14 in. • D. 21 in.
3. Study Figures I and II. Determine which transformation, if any, of Figure I is shown in Figure II. • A. Rotation • B. Reflection • C. Translation • D. No transformation Figure I Figure II
4. Give the coordinates of point A on the graph. • A. (-5, 2) • B. (2, -4) • C. (2, -5) • D. (1, -5) A
5. Which point shown on the graph has the coordinates (4, -1)? • A. point A • B. point B • C. point C • D. point D •B •D •C •A
6. Find the missing length (x) for the pair of similar figures shown. • A. 16 cm • B. 24 cm • C. 36 cm • D. 48 cm 24 cm 12 cm 8 cm x
7. Look at the similar figures shown below. Which ratio gives the correct value for any two sides within each square? • A. 1:1 • B. 1:5 • C. 5:1 • D. 5:20 25 5 5 25
8. Give the coordinates of point C on the graph. • A. (2, 3) • B. (3, 2) • C. (1, 3) • D. (3, 1) •C
Solutions • 1. C – this figure has been slid (translated) • 2. D – if the height is enlarged from 5 to 15, it is three times its original size. If the length is 7, it will be enlarged to 21 • 3. B – the figure is reflected; it is a mirror image • 4. C – the coordinates for point A are (2, -5) • 5. C – point C has the coordinates (4, -1)
Solutions, continued • 6. A – the two figures are similar parallelograms with ratio 1:2. If the length of the first figure is 8, the length of the second is doubled to 16. • 7. A – all sides are equal on a square, therefore the ratio is 1:1. • 8. A – the coordinates for point C are (2, 3)
