West Bengal Board Solutions for Chapter: Construction of Triangles, Exercise 1: Let's Work Out - 21

Let's draw a triangle whose two sides are $6 \mathrm{cm} \text{and} 7 \mathrm{cm}$, and the measurement of the angle opposite to the side of length $7 \mathrm{cm}$ is $60°$. Let's write what will be the measurement of the sides to form a triangle.

Let's construct a triangle whose lengths of two sides are $6 \mathrm{cm} \text{and} 9 \mathrm{cm}$ and the measurement of the angle opposite to the side of length $9 \mathrm{cm}$ is $105°$. Let's write for what length of sides we will not be able to construct a triangle.
