In an isosceles triangle if a base angle is twice the vertical, calculate the angles of the triangle

In ΔABC, AC = BC. Then value of x is 

In ΔABC, AB = AC and ∠B is more than 30^o but less than 45^o .Then m∠C cannot be

In the adjoining figure, ∠ ABC = ∠BDC = 90^o & BD = DC then the value of ∠DBC is

If AB = AC and ∠A = 50^o. Then measure of ∠ABC is 

If AB = AC and ∠B = 43^o. Then measure of ∠ACB is 

If ∠Y = ∠Z, YZ = 12cm and perimeter of ΔXYZ = 38cm. Then length of XZ is

In the given figure AB = AC and AD⊥BC. Which criterion can be used to prove congruency of shaded and unshaded triangles. 

If PQ = QR and ∠P = 37 1/2^o. Then measure of ∠PQR is 

In an isosceles right angled triangle, state the measure of equal angles
