For each figure, identify any angles of rotation that create symmetry.

G.CO.3

A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select all conclusions that we can reach from this.

All angles of the triangle have the same measure.

All sides of the triangle have the same length.

All rotations take one half of the triangle to the other half of the triangle.

G.CO.3

Select all the angles of rotation that produce symmetry for this flower.

G.CO.3

Identify any lines of symmetry the figure has.

G.CO.3

A triangle has a line of symmetry. Select all conclusions that must be true.

No angles of the triangle have the same measure.

All sides of the triangle have the same length.

Two sides of the triangle have the same length.

G.CO.3

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