Figures with same shape are called

Each of the interior angle of a regular pentagon is

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

If in ΔABC,∠A = 50^o and ∠B = ∠C then ∠B =

The sum of the exterior angles of a polygon is

If ∠ABC = ∠DEF then ∠DEF = ∠ABC. Name this property.

In Δ PQR, QR = PR then
