Triangles Test ...

In the given figure, triangles $$ABC$$ and $$DCB$$ are right angled at $$A$$ and $$D$$ respectively and $$AC$$ $$=$$ $$DB$$, then $$\Delta$$ $$ABC$$ $$\cong\Delta$$ $$DCB$$ of from.

The ________ criterion is used to construct a triangle congruent to another triangle whose length of three sides are given.

In $$\triangle ABC$$, if $$AB = 7$$ cm, $$\angle A= 40^o$$ and $$\angle B = 70^o$$, which criterion can be used to construct this triangle?

If $$ \triangle ABC$$ and $$\triangle DBC$$ are on the same base BC,AB=DC and AC=DB,then which of the following gives a CORRECT congruence relationship?

Which of the following triangles is congruent to the given triangle?

Two triangles are congruent, if two angles and the side included between them in one triangle is equal to the two angles and the side included between them of the other triangle.This is known as

In a triangle ABC , if AB , BC and AC are the three sides of the triangle , then which of the following statements is necessarily true ?

In the given figure, $$B < A$$ and $$D > C$$, then:

If $$D$$ and $$E$$ are the mid-points of the sides $$AB$$ and $$AC$$ respectively of $$\triangle ABC$$. $$DE$$ is produced to $$F$$. To prove that $$CF$$ is equal and parallel to $$DA$$, we need an additional information which is:

$$AB$$ and $$CD$$ are the smallest and largest sides of a quadrilateral $$ABCD$$.
