Card 1Lines of Symmetry in Triangles

How many lines of symmetry does an equilateral triangle have?

Answer

An equilateral triangle has 3 lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. Since all sides and angles are equal, folding along any of these …

Card 2Symmetry in Quadrilaterals

Draw a rectangle and show all its lines of symmetry.

Answer

A rectangle has 2 lines of symmetry. Step 1: Draw a rectangle ABCD. Step 2: One line of symmetry is the perpendicular bisector of the longer sides (vertical). Step 3: The second line is the perpendic…

Card 3Symmetry in Letters

Which letter among A, B, C, D has only one line of symmetry?

Answer

All of the letters A, B, C, and D have exactly one line of symmetry each. Explanation: - A: One vertical line of symmetry - B: One horizontal line of symmetry - C: One horizontal line of symmetry - D…

Card 4Symmetry in Triangles

Does a scalene triangle have any line of symmetry? Why or why not?

Answer

No, a scalene triangle does not have any line of symmetry. Reason: In a scalene triangle, all sides and angles are different. There is no way to fold the triangle so that one half exactly matches the…

Card 5Symmetry in Squares

Find the number of lines of symmetry in a square.

Answer

A square has 4 lines of symmetry. Explanation: 1. Two diagonals (from corner to opposite corner) 2. One vertical line through midpoints of left and right sides 3. One horizontal line through midpoint…

Card 6Constructing Symmetric Points

Construct the symmetric point of P with respect to line AB.

Answer

Steps: 1. Draw perpendicular from point P to line AB. Let it meet AB at point O. 2. Extend PO beyond O to point Q such that OQ = OP. 3. Point Q is the symmetric point of P with respect to AB. Verific…

Card 7Symmetry in Circles

How many lines of symmetry does a circle have?

Answer

A circle has infinite lines of symmetry. Explanation: Every diameter (line passing through the center) acts as a line of symmetry. You can fold the circle along any diameter and both halves will matc…

Card 8Symmetry in Letters

Which of the following has two lines of symmetry: H, O, X, Z?

Answer

All of H, O, and X have two lines of symmetry. Z has none. Breakdown: - H: Vertical and horizontal - O: Infinite (but at least two) - X: Two diagonals - Z: No line of symmetry So correct answer: H, …
