Which of these is an isosceles
triangle?
In this question, we’re shown two
different triangles, triangle A and triangle B. And we’re asked which of them is an
isosceles triangle. Let’s think about what we know
about isosceles triangles. This is an isosceles triangle. An isosceles triangle has two equal
sides. So, which of our two triangles is
an isosceles triangle? Is it triangle A or triangle B? It’s triangle A. These two sides are equal in
length. This triangle has two longer sides,
which are the same length, and one shorter side. The isosceles triangle is triangle
A.
