Question

question #3 which of the following images has both point and line symmetry?

Explanation:

Step1: Define point and line symmetry

Point - symmetry means the figure looks the same after a 180 - degree rotation about a point. Line - symmetry means there is a line such that the figure can be folded along that line and the two halves match exactly.

Step2: Analyze the star

The star has line - symmetry (multiple lines passing through the center and vertices), but it does not have point - symmetry as a 180 - degree rotation will not map it onto itself.

Step3: Analyze the book

The open book has line - symmetry (a vertical line through the center of the book), but no point - symmetry as a 180 - degree rotation will not map it onto itself.

Step4: Analyze the blue shape

The blue shape has point - symmetry (a 180 - degree rotation about its center maps it onto itself) and also has multiple lines of symmetry passing through its center.

Step5: Analyze the heart

The heart has line - symmetry (a vertical line through the center of the heart), but no point - symmetry as a 180 - degree rotation will not map it onto itself.

Answer:

The blue shape
