Congruence of two triangles

Write down the conditions of congruency of two triangles.

Explain with the figure whether angle-angle-angle can be a condition for congruency of two triangles.

Use the information marked to prove : (i) DeltaEAC cong DeltaDBC (ii) EC = DC Also state the Euclid's axiom used in proving the congruency of two triangles.

Side Angle Side (SAS) Congruence - Two triangles are congruent if two sides and the included angle of one are equal to the corresponding sides and the included angle of the other triangle.

Side Side Side(SSS) Congruence : Two triangles are congruent if the three sides of one triangle are equal to the corresponding three sides of the other triangle.
