Question

draw in all lines of symmetry in the shape below. if there are no lines of symmetry, submit an answer without drawing them in. plot a line by clicking in two locations. click a line to delete it.

Explanation:

Step1: Recall line - symmetry concept

A line of symmetry divides a shape into two congruent parts.

Step2: Analyze the given triangle

The given triangle is isosceles. For an isosceles triangle, the line that passes through the vertex opposite the base and the mid - point of the base is a line of symmetry.

Step3: Determine the number of lines of symmetry

This isosceles triangle has 1 line of symmetry as described above.

Answer:

There is 1 line of symmetry which is the vertical line passing through the top vertex and the mid - point of the base of the triangle.
