EXERCISE 10.3

Construct $\mathrm{\Delta }\mathrm{D}\mathrm{E}\mathrm{F}$ such that $\mathrm{D}\mathrm{E}=5\mathrm{}\mathrm{c}\mathrm{m},\mathrm{D}\mathrm{F}=3\mathrm{}\mathrm{c}\mathrm{m}$ and $\mathrm{m}\mathrm{\angle }\mathrm{E}\mathrm{D}\mathrm{F}={90}^{\mathrm{o}}$.

Construct an isosceles triangle in which the lengths of each of its equal sides is $6.5\mathrm{}\mathrm{c}\mathrm{m}$ and the angle between them is ${110}^{\mathrm{o}}.$

Construct $\mathrm{\Delta }\mathrm{A}\mathrm{B}\mathrm{C}$ with $\mathrm{B}\mathrm{C}=7.5 \mathrm{c}\mathrm{m}, \mathrm{A}\mathrm{C}=5 \mathrm{c}\mathrm{m}$ and $\mathrm{m}\mathrm{\angle }\mathrm{C}={60}^{\mathrm{o}}.$
