**Congruence of Triangles** - Class 6 Mathematics CBSE ICSE

Improve your understanding of

**Congruence of Triangles**by practicing the below questions from class 6 Mathematics.###### Two triangles are congruent if two angles and the side included between them in one of the triangles are equal to the corresponding angles and the side included between them of the other triangle. The above property is known as

###### Which congruence criterion do you use in the following?

Given: angle MLN = angle PQR

angle NML =angle QPR

ML = PQ

$\mathrm{So},$$\Delta \mathrm{PRQ}$$\Delta \mathrm{ACB}\mathrm{using}\mathrm{the}\mathrm{property}$.

###### Two triangles are congruent if the three sides of the one are equal to the three corresponding sides of the other.The above property is known as

###### If two triangles have their corresponding angles equal, then they are always congruent.

###### Which congruence criterion do you use in the following?

Given: EB = DB

AE = DC

angle A= angle C = 90^{0}

$\mathrm{So},$$\Delta \mathrm{ABE}$ is congruent to $\Delta \mathrm{CDB}\mathrm{using}\mathrm{the}\mathrm{property}$

###### You need to show that Δ ABC $\Delta \mathrm{PQR}\mathrm{using}\mathrm{SAS}\mathrm{criterion}.$

We have angle C = angle R, BC =QR. What is the third statement?

###### Which congruence criterion do you use in the following?

Given: AC = DF

AB = DE

BC = EF

$\mathrm{So},$$\Delta \mathrm{ABC}$#cong $\Delta \mathrm{DEF}\mathrm{using}\mathrm{the}\mathrm{property}$

###### If _{$\Delta $}ABC and _{$\Delta $}PQR are to be congruent, name one additional pair of corresponding parts.
