Answer 1

1-We know that in a right angle triangle,

The sum of the squares on two sides of a triangle is equal to the square on the third side, then the triangle is a right angle.

$\small{ \boxed{ \boxed{\bold \red{Base^2 +Prependicular^2 =Hypotenuse^2}}}}$

Now, we go to the options,

$1) \: {3}^{2} + {4}^{2} = {5}^{2}$

$2) \: {5}^{2} + {12}^{2} = {13}^{2}$

$3) \: {10}^{2} + {24}^{2} = {26}^{2}$

$4) \: {9}^{2} + {24}^{2} = {26}^{2}$

$5) \: {9}^{2} + {40}^{2} = {41}^{2}$

$6) \: {20}^{2} + {25}^{2} \ne {30}^{2}$

All are right angle triangle except 20,25,30

$\bold{2-i - \angle A+\angle B+\angle C}$

$70 \degree + 50 \degree + x = 180 \degree$

$x = 180 \degree - 120 \degree = 60 \degree$

$x = 60 \degree$

$\bold{ii - \angle P+\angle Q+\angle R}$

$90 \degree + 20\degree + x$

$x = 180 \degree - 110 \degree$

$x = 70 \degree$
