GCSE Maths - Lines of Symmetry #98

The video tutorial explains the concept of symmetry in mathematics, focusing on how objects can be symmetrical with a line of symmetry dividing them into mirror images. It uses basic shapes like isosceles triangles, rectangles, and equilateral triangles to illustrate the concept. The isosceles triangle has one line of symmetry, the rectangle has two, and the equilateral triangle has three. The tutorial provides a method to identify lines of symmetry by drawing a line and checking if the two sides are symmetrical.

Explain how to determine if a shape has a line of symmetry.

What are the lines of symmetry for an equilateral triangle?
