A pair of triangles is shown. Equal parts of triangles are marked with the same signs. Observe the figures and state the test by which the triangles in the given pair is congruent.

Observe the information shown in pairs of triangles given below. State the test by which the two triangles are congruent. Write the remaining congruent parts of the triangles.

From the information shown in the figure, in ΔABC and ΔPQR

 
∠ABC ≅ ∠PQR

 
seg BC ≅ seg QR

 
∠ABC = ∠PRQ

 
∴ ΔABC ≅ ΔPQR ……………………____ test

 
∴ ∠BAC = _____……………………corresponding angles of congruent triangles.

 
seg AB ≅ ____………………….. corresponding sides of congruent triangles.

 
____ = seg PR …………………corresponding side of congruent triangles.

Observe the information shown in pairs of triangles given below. State the test by which the two triangles are congruent. Write the remaining congruent parts of the triangles.

From the information shown in the figure.,

 In $△PTQ=△STR$

 $\angle PTQ=\angle STR$ ..... vertically opposite angles

 seg $TQ\cong$ seg $TR$

 $△PTQ\cong △STR$....._____ test

$\angle TPQ\cong$ _____ .....corresponding angles of congruent triangles.

_____ $\cong \angle TRS$ .....corresponding angles of congruent triangles.

seg $PQ\cong$ _____ ..... corresponding sides of congruent triangles.

From the information shown in the figure, state the test assuring the congruence of $△ABC$ and $\Delta PQR$. Write the remaining congruent parts of the triangles.

As shown in the following figure, in $△LMN$ and $△PMN, LM=PN, LN=PM$. Write the test which assures the congruence of the two triangles. Write their remaining congruent parts

In figure, $\mathrm{seg} AB\cong \mathrm{seg} CB$ and $\mathrm{seg} AD\cong \mathrm{seg} CD$. 

Prove that $△ABD\cong △CBD$.
