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.
