Class - 7 - Lines and Angles

The angles between North and West with South and East are

• Complementary

• Supplementary

• both are acute

• both are obtuse

Angle between South and West with South and East is

• vertically opposite angles

• complementary

• making a linear pair

• adjacent but not supplementary

Angles which are both supplementary and vertically opposite are

• $95\degree,\ 85\degree$

• $90\degree,\ 90\degree$

• $100\degree,\ 80\degree$

• $45\degree,\ 45\degree$

Find the value of 'x'.

• $110\degree$

• $46\degree$

• $64\degree$

• $150\degree$

Which of the following is false?

• $\angle a=\angle b$

• $\angle d=\angle c$

• $\angle a+\angle d=180\degree$

• $\angle a=\angle d$

Find the value of 'a'.

• $40\degree$

• $45\degree$

• $55\degree$

• $60\degree$

If POQ is a line and x = 30 $\degree$  Find  $\angle$  QOR

•  $90\degree$  

•  $30\degree$  

•  $150\degree$  

•  $60\degree$  

If two supplementary angles are in the ratio 1:2 then, the bigger angle is

• $120\degree$

• $125\degree$

• $110\degree$

• $90\degree$

p : 'a' and 'b' are forming a linear pair

q : 'a' and 'b' are forming a pair of adjacent angles

then,

• both p and q are true

• p is true and q is false

• p is false and q is true

• both p and q are false

Vertically opposite angles are always

• complementary

• supplementary

• adjacent

• equal
