Construct a triangle with the same measurements given in the above example, taking $PQ$ as the base. Are the triangles congruent?

Construct a $∆XYZ$ in which $XY=6 \mathrm{cm}$, $YZ=8 \mathrm{cm}$ and $ZX=10 \mathrm{cm}$. Using a protractor find the angle at $Y$. What type of triangle is this?

Construct a $∆ABC$ in which $AB=6 \mathrm{cm}$, $BC=7 \mathrm{cm}$ and $CA=3 \mathrm{cm}$. Which type of triangle is this?

Sushanth prepared a problem: Construct $∆XYZ$ in which $XY=2 \mathrm{cm}, YZ=8 \mathrm{cm}$ and $XZ=4 \mathrm{cm}$.
He also drew the rough sketch as shown in Figure $1$.

Reading the problem, Srija told Sushanth that it would not be possible to draw a triangle with the given measurements. However, Sushanth started to draw the diagram as shown in Figure $2$.

Check whether Sushanth can draw the triangle. If not, why? Discuss it with your friends. What property of triangles supports Srija's idea?
