Can someone please help me with these, I find them very difficult to do.

1. Bob says that all octagons have rotational symmetry. Is he correct? Justify your answer. (An illustration may be very helpful here.)2. Which of following statement(s) are true? I. An object can have rotation symmetry. II. An object can have dilation symmetry. III. An object can have reflection symmetry. I, II, and III O I and II I and III Only II3. Reflecting a shape over the x-axis and then over the y-axis has the same result as which of the following? O Reflection over the line y = x. O Rotation of 360" about the origin O Rotation of 180 about the origin O None of the above4. Bob says that reflecting an object over the x-axis and then rotating it 180"gives the same result as rotating it 180"and then reflecting it over the x-axis. Is he correct? Justify your answer by showing an example. Based on this, do you believe that compositions of transformations are commutative? Why?5. Which of the following shapes only has one line of symmetry? O Square O Oval O Isosceles Triangle O Equilateral Triangle6. Sally says that a regular hexagon can be rotated 60" about its center to show rotational symmetry. John says that a regular hexagon can be rotated 120" about its center to show rotational symmetry. Who is correct? Justify your answer.7. How many lines of symmetry does the letter "H" have? No lines of symmetry One line of symmetry Infinite lines of symmetry Two lines of symmetry 8. Which of the following set of points would result from rotating AABC about the origin 90 counterclockwise and then reflecting it over the x-axis? A (2, 5) B (4, 1) C (6, 5) A" (-2, 5) B"(-4, 1) C"(-6, 5) A" (2, -5) B"(4, -1) C"(6, -5) A" (5, -2) B"(1, -4) C"(5, -6) O A"(-5, -2) B"(-1, -4) C"(-5, -6)
