# __________ triangle is a figure that has a line of symmetry but lacks rotational symmetry.

**Solution:**

We know that

Isosceles triangles are those triangles that have at least two sides of equal measure.

The line of symmetry is a line that divides an object into two identical pieces.

Therefore, an isosceles triangle is a figure that has a line of symmetry but lacks rotational symmetry.

**✦ Try This: **____ is a figure that has 7 lines of symmetry.

We know that

Number of lines of symmetry in a regular pentagon is equal to the number of sides of a polygon.

As a heptagon has 7 sides it has 7 lines of symmetry.

Therefore, a heptagon is a figure which has 7 lines of symmetry.
