Author:GeoGebra Classroom Activities, IM Algebra 1, Geometry, Algebra 2

Which of these constructions would construct a line of reflection that takes the point  to point ?

Select all that apply
  • A
  • B
  • C
  • D
Check my answer (3)

A point  stays in the same location when it is reflected over line . What can you conclude about ?

Lines  and  are perpendicular with point of intersection . Noah says that a 180 degree rotation, with center , has the same effect on points in the plane as reflecting over line . Do you agree with Noah? Explain your reasoning.

Here are 4 triangles that have each been transformed by a different transformation. Which transformation is not a rigid transformation?

Select all that apply
  • A
  • B
  • C
  • D
Check my answer (3)

There is a sequence of rigid transformations that takes A to A', B to B', and C to C'. The same sequence takes D to D'. Draw and label D'.

Here are 3 points in the plane.

Explain how to determine whether point C is closer to point  or point .
