Question

Draw a triangle which has only one line of symmetry? what is this this triangle called?

Answer 1

The division of triangles into scalene, isosceles, and equilateral can be thought of in terms of lines of symmetry. A scalene triangle is a triangle with no lines of symmetry while an isosceles triangle has at least one line of symmetry and an equilateral triangle has three lines of symmetry

Answer 2

Hey mate,
Here's your answer

Here's the figure showing a triangle having one line symmetry.

Now since this has one line of symmetry,
So the two sides of the triangle on the either sides of the line of symmetry must be equal.

And as we know a triangle having two sides equal is called as Isosceles triangle.
So this triangle is an isosceles triangle.

Hope this helps!

Thank you
