Answer 1

We know In a Right angle triangle longest side is hypotenuse which is 3.5cm.and perpendicaular is 2.1cm and base is 2.8cm.

$\: \: \: \: \: \: \: \sf{\pink{by \: pythagoras \: theorm}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{ {h}^{2} = {p}^{2} + {b}^{2} }$

$\: \: \: \: \: \: \: {(3.5)}^{2} = {(2.1)}^{2} + {(2.8)}^{2}$

$\: \: \: \: \: \: \: \: \sf {12.25 = 4.41 \: + \: 7.84}$

$\: \: \: \: \: \: \: \: \: \sf{12.25 = 12.25}$

As H² = P² + B² So The triangle is a right angle triangle.
