The properties of rational numbers -

[Choose all the right options]

• Can be expressed in the form of p/q

• There can be infinite rational numbers between two rational numbers.

• Any terminating decimal is a rational number.

• Any non-terminating decimal is a rational number.

• Any recurring and non-terminating decimal is a rational number.

 $\sqrt{9}\ +\ 2\sqrt{5}\ =\ a\ +\ b√5$  The rational values of "a' and "b" in the given equality is

•  $a\ =\ 9,\ b\ =\ 2$  

•  $a\ =\ 3\ ,\ b\ =\ \sqrt{2}\$  

•  $a\ =\ \sqrt{3}\ ,\ b\ =\ 5$  

•  $a\ =\ 3\ ,\ b\ =\ 2$  

 $\frac{1}{\sqrt{4}\ +\ \sqrt{5}}\ =\ a\ -b\sqrt{5}$  , the rational values of 'a' and 'b" 

•  $a\ =\ 2,\ b\ =-5$  

•  $a\ =\ -4\ ,\ b\ =\ -\ 2$  

•  $a\ =\ -2\ ,\ b\ =\ -\frac{1}{3}$  

•  $a\ =\ -2\ ,\ b\ =\ -1$  

Irrational numbers are

• non-terminating

• non- recurring

• always recurring

• always terminating

 $Is\ it\ true\ that\ \ \angle f=\angle b+\angle e?$   If yes, which of these explains why? [For the triangle that lies between the parallel lines] 

•  $YES,\ \ \angle f=\angle b+\angle c\ \ \ and\ \ \ \angle c=\angle e$  

•  $Yes;\ \ As\ \ \angle f=\angle b\ \ \ \ and\ \ \angle c=\angle e$  

• The given statement is not true.

•  $Yes;\ \ As\ \ \angle f=\angle b\ \ and\ \ \angle e=\angle b+\angle c$  

 $\angle b\ :\ \angle a\ =\ 2\ :\ 3,\ then\ \angle b\ =\ ?$  

•  $72\degree$  

•  $118\degree$  

•  $36\degree$  

•  $70\degree$  

 $AB\ \parallel\ CD,\ find\ \angle x$  

•  $105\degree$  

•  $115\degree$  

•  $130\degree$  

•  $135\degree$
