If $\mathrm{PAB}$ is an intersecting line which intersects the circle at points $\mathrm{A} \& \mathrm{B}$. $\mathrm{PT}$ is a tangent then $\mathrm{PA}\times \mathrm{PB}$ will be:

Two circles touch each other internally. If their radii are $2 \mathrm{cm} \& 3 \mathrm{cm}$. Find the length of that chord of larger circle which touches the smaller one:

$\mathrm{x}, \mathrm{x}+1$ and $\mathrm{x}-1$ are the sides of a right-angled, $\mathrm{\Delta }$ then its hypotenuse will be:

$\mathrm{ABCD}$ is a rectangle & $∆\mathrm{ABP}$ is a right angled $∆$, $\angle \mathrm{PAB}=60°$ then find $\angle \mathrm{PDC}$:

If in the given figure $\mathrm{AB}\Vert \mathrm{DC}$ then find the value of $\angle \mathrm{ADC}$:

If $\mathrm{O}$ is the centre of circle then $\angle \mathrm{BOD}=?$

What will be the value of $\mathrm{x}$:

In an equilateral $\mathrm{\Delta }$ incentre, circumcentre and orthocentre are:
