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 $$AB$$.
