Question

If the terminal arm of a standard angle lies along any type of coordinate axes ,then it is called as A-ZERO ANGLE. B-STRAIGHT ANGLE.C-COTERMINAL ANGLE.D-QUADRANTAL ANGLE​

Answer 1

If the terminal arm of a standard angle lies along any type of coordinate axes ,then it is called as Quadrantal angle

This way, 0, 90, 180, 270, 360 degrees are all Quadrantal angles.

a) Zero angle : When the arms of a triangle that is, Both initial and final coincide then it is called Zero angle.

b) Straight angle : When the arms of a angle are inclined at half rotation or 180 degrees, It is said to be straight angle.

c) Co terminal angles : When all the given angles have same co terminal side then, We can say they are co terminal angles.

Answer 2

Step-by-step explanation:

Q.1 Select & Write the correct answer.

i) It the terminal arm of a standard angle lies along any of the co-ordinates axes then it is called.

a) Zero angle

ii) It tan Q+ 1

b) Right angle

c) Quatrantal angle d) Straight angle

=2 then find the value of
