The Triangle an...

In $\Delta ABC, BC=AB$ and $\angle B=80^{o}.$ Then $\angle A$ is equal to

In $\Delta PQR, \angle R=\angle P$ and $QR$ $=4$ cm and $PR$ $= 5$ cm. then what is the length of $PQ$ ?

Two sides of a triangle are of lengths $4$ cm and $1.5$ cm. The length of the third side of the triangle cannot be

The construction of a triangle $ABC$, given that $BC =$ $6$ cm, $B =$ $45 ^{\circ}$ is not possible when difference of $AB$ and $AC$ is equal to:

If lengths of sides of a triangle are 6, 10, 8, then ABC is .........triangle.

Which of the following is NOT the length of a

median in triangle ABC with vertices A(1,3), B(1,1) and C(5,1)?

From the adjoining figure, calculate the values of $a$.

In $\Delta$ ABC, $\angle B = 90 ^\circ$, AB = 6 cm and BC = 8 cm. The length of AC is

If length of the largest side of a triangle is 12 cm then other two sides of triangle can be 

In the given figure, $ABC$ is a triangle, side $CB$ is produced to $E$ and $\angle A$: $\angle B$: $\angle C$ $= 2: 1: 3$. Find $\angle DBE$, if $DB$ is perpendicular to $AB$.
