Explanation:

Determine congruence or similarity of the stars

The two green stars have the exact same shape and the exact same size. Therefore, they are congruent.

Match transformation terms to definitions

• Slide: Moving the figure to another location (Translation).
• Transformation: Movement of a figure that doesn't change the shape or size (specifically rigid transformation, or general transformation in this context).
• Rotation: Object stays the same, but is now facing a different direction (turning around a point).
• Reflection: Figure is moved by flipping it over an imaginary line.

Identify letters with line symmetry

• B: Has a horizontal line of symmetry.
• N: Has rotational symmetry, but no line of symmetry.
• D: Has a horizontal line of symmetry.
• A: Has a vertical line of symmetry.
• K: Has a horizontal line of symmetry (in standard sans-serif/serif print fonts, K is symmetric horizontally).

Answer:

Question 1

congruent

Question 2

• Slide: Moving the figure to another location
• Transformation: Movement of a figure that doesn't change the shape or size
• Rotation: Object stays the same, but is now facing a different direction
• Reflection: Figure is moved by flipping it over an imaginary line

Question 3
