Question

consider the letters of the word math.
the letter m has line(s) of symmetry.
the letter a has line(s) of symmetry.
the letter t has line(s) of symmetry.
the letter h has line(s) of symmetry.

Explanation:

Step1: Analyze letter M symmetry

A vertical line through the center of M divides it into two mirror-image halves; no other lines work.

Step2: Analyze letter A symmetry

A vertical line through the center of A divides it into two mirror-image halves; no other lines work.

Step3: Analyze letter T symmetry

A vertical line through the center of T divides it into two mirror-image halves; no other lines work.

Step4: Analyze letter H symmetry

A vertical line through the center and a horizontal line through the center of H both divide it into mirror-image halves.

Answer:

The letter M has 1 line(s) of symmetry.
The letter A has 1 line(s) of symmetry.
The letter T has 1 line(s) of symmetry.
The letter H has 2 line(s) of symmetry.
