In which of the following figures, only perpendicular is shown?

In which of the following figures, bisector is shown?

In which of the following figures,

Perpendicular bisector is shown?

Copy the isosceles triangle $\mathrm{ABC}$ shown in Figure on your notebook. Take a point $\mathrm{E}$ on $\mathrm{BC}$ and draw $\mathrm{EF}$$\perp \mathrm{CA}$ and $\mathrm{EG} \perp \mathrm{AB}$

Measure $\mathrm{EF}$ and $\mathrm{EG}$and add them. Draw $\mathrm{AD}\perp \mathrm{BC}$

Check whether the sum of $\mathrm{EF}$ and $\mathrm{EG}$ is equal to $\mathrm{AD}$ with the help of ruler or with the help of divider.

Copy the equilateral $△$$\mathrm{ABC}$ shown in figure on your notebook.

Draw $\mathrm{AK}\perp \mathrm{BC}$. Take $\mathrm{P}$ as shown in the figure. Draw $\mathrm{PD}\perp \mathrm{BC} , \mathrm{PE}\perp \mathrm{CA}$ and $\mathrm{PF}\perp \mathrm{AB}$

Verify $\mathrm{AK}=(\mathrm{PD}+\mathrm{PE}+\mathrm{PF})$ with the help of divider and ruler.
