Composition of Transformations Symmetry

What is the transformation from Triangle ABC to Triangle A''B''C''?

• Reflection x-axis, then rotation of 180 Degrees

• Reflection over y-axis, then rotation of 90 Degrees

• Rotation of 90 Degrees, then reflection over x-axis

• Rotation of 180 Degrees, then reflection over y-axis

when you reflect one side of the figure across a drawn line and it coincides with the other side, this line is called...

• line of symmetry

• axis of symmetry

• line symmetry

• symmetry

every point "reflected" through a central point aligns with another point of the figure

• rotational symmetry

• order of symmetry

• magnitude of rotational symmetry

• point symmetry

can be mapped onto itself using a rotation with a magnitude less than or equal to 180*

• rotational symmetry

• order of symmetry

• magnitude of rotational symmetry

• point symmetry

divides the object into two identical halves that are reflections of each other

• plane symmetry

• plane of symmetry

• rotational symmetry

• point symmetry

• J"(0,6), K"(1,-3), L"(3,5)

• J"(3,1), K"(2,-2), L"(0,0)

• J"(10,6), K"(9,3), L"(7,5)

• J"(-5,1), K"(-4,-2), L"(-2,0)
