Congruence of T...

Ankita wants to prove $$\Delta ABC\cong \Delta DEF$$ using $$SAS$$. She knows $$AB=DE$$ and $$AC=DF$$. What additional piece of information does she need?

By which congruency property, the two triangles connected by the following figure are congruent.

In the given fig. if AD = BC and AD || BC, then:

ABC is an isosceles triangle in which the altitudes $$BE$$ and $$CF$$ are drawn to the equal sides $$AC$$ and $$AB$$ respectively. Then

In the following fig. if AB = AC and BD = DC then $$\angle ADC\, =$$

In the given figure, $$\triangle RTQ\cong \triangle PSQ$$ by ASA congruency condition. Which of the following pairs does not satisfy the condition?

It is given that $$AB=BC$$ and $$AD=EC.$$ The $$\triangle ABE\cong \triangle  CBD$$ by __________ congruency.

In the given figure, $$OA=OB, OC=OD, \angle AOB=\angle COD.$$ Which of the following statements is true$$\: ?$$

In the figure, $$\displaystyle \Delta ABC\cong \Delta ADC$$ by the congruence postulate

For a $$\displaystyle \Delta XYZ, ZY = 12\ m, YX = 8\ m$$ and $$XZ = 10\ m$$. If $$\displaystyle \Delta ZYX\cong \Delta ABC$$, then $$AC =$$ _____ $$m$$.
