Front

What are transformations in geometry?

Back

Transformations are when you turn, flip, or slide a shape on a graph.

Front

What does clockwise mean?

Back

Clockwise means the same direction that the hands of a clock move.

Front

Back

The missing angle is 50 degrees.

Front

Are these angles vertical? (yes/no)

Back

No.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect.

Front

What is a transformation that flips a shape called?

Back

A reflection.

Front

What is the sum of angles in a triangle?

Back

The sum of angles in a triangle is always 180 degrees.

Front

What is a rotation in geometry?

Back

A rotation is turning a shape around a fixed point.
