# Which type of triangle will always have exactly 1-fold reflectional symmetry?

Symmetry is defined as a proportionate and balanced similarity that is found in two halves of an object; that is, one-half is the mirror image of the other half.

## Answer: An Isosceles Triangle is a type of triangle that will always have exactly 1-fold reflectional symmetry

Let's look at the full explanation below.

**Explanation:**

- When a figure may be folded over into itself in a line, it is said to have reflection symmetry. This line is called the line of symmetry.
- The number of symmetry lines in a regular polygon is proportional to the number of sides in the polygon.
- An isosceles triangle is a type of triangle that has exactly one-fold reflection symmetry at all times.
- One line or one division will break the whole figure into two symmetrical parts, which is known as 1-fold reflection symmetry.
- A triangle with two sides of equal length is called an isosceles triangle. At least one symmetry line exists in an isosceles triangle.
