Chapter 14.8, Problem 8CE

To determine

To show the all symmetries of the isosceles triangle.

Answer to Problem 8CE

The isosceles triangle has one line of symmetry.

Explanation of Solution

Given information:

The figure is isosceles triangle.

A figure in the plane has symmetry if there is an isometry, other than the identity, that maps the figure onto himself.

The symmetry of the isosceles triangle is given below,

The isosceles triangle is symmetry along the perpendicular bisector which gives two halves identical,

Therefore, the isosceles triangle has one line of symmetry.
