In figure , BC is extended to D.Then ∠ACD =

An angle is 18^o less than its complementary angles, the measure of this angle is

∠ABD and ∠CBD form a linear pair of angles if A,B and C are 

In figure if l || m, the value of x is

If angles (2x - 10 )^o and (x - 5 )^o are complementary angles , the value of x is

If ∠X = 90^o - ∠Y , then ∠X and ∠Y are _________ angles.

An angle which is greater than 180^o and less than 360^o is called a 

In figure of l || m , then value of x is

If two parallel lines are intersected by a transversal, then interior , angles on the same side of the transversal are 

If three or more points lie on the same line,they are called
