State which of the following are triangles.
$ \overline{A B}=7 \mathrm{~cm}, \overline{B C}=8 \mathrm{~cm}, \quad \overline{A C}=7 \mathrm{~cm} $


Given:

\( \overline{A B}=7 \mathrm{~cm}, \overline{B C}=8 \mathrm{~cm}, \overline{A C}=7 \mathrm{~cm} \)

To do:

We have to find if the given measurements form a triangle.

Solution:

In the given triangle,

\( \overline{A B}=7 \mathrm{~cm}, \overline{B C}=8 \mathrm{~cm}, \overline{A C}=7 \mathrm{~cm} \)

Let us draw a rough figure,

As we can see from the figure, $\triangle ABC$ is an isoceles triangle.
