Line of symmetry

Step 1: We need to identify the name of the line that divides a shape into two equal mirror halves. Step 2: When a line divides a shape so that folding along it makes both halves match exactly, that line has a special name. Step 3: This line is called the Line of Symmetry. Step 4: A shape can have one or more lines of symmetry. For example, a square has 4 lines of symmetry, a rectangle has 2, and a circle has infinite lines of symmetry. Final Answer: The line is called the Line of Symmetry.

Countless (infinite)

Step 1: We need to find how many lines of symmetry a circle has. Step 2: A line of symmetry divides a shape into two equal mirror halves. Step 3: For a circle, any line passing through its centre divides it into two equal halves. Step 4: Since we can draw as many lines as we want through the centre, there are infinite (countless) lines of symmetry for a circle. Final Answer: A circle has infinite (countless) lines of symmetry.

At least one line of symmetry along the fold

Step 1: When Riya folds the paper and puts colour on the fold line, the colour spreads on both sides of the fold equally. Step 2: When she opens the paper, both sides have exactly the same colour pattern. Step 3: This means the fold line divides the pattern into two equal mirror halves. Step 4: Therefore, the fold line is a line of symmetry for the pattern. Final Answer: The pattern will always have at least one line of symmetry along the fold line.
