A triangle can always possess

Name this properly " Every triangle is congruent to itself".

Name the properly " If Δ ABC≅ ΔDEF; Δ DEF ≅ Δ KLN then Δ ABC ≅ Δ KLN."

Each of the interior angle of a regular pentagon is

In the figure ∠x =

The sum of the exterior angles of a polygon is

If in Δ ABC, Δ DEF ; AB = DE ; AC = DF and ∠A = ∠D then Δ ABC≅ Δ DEF by ________ axiom.

In Δ PQR, QR = PR then

If in Δ ABC, AB = AC and vertical angle is 40^o, then base angles are
