Question

Keelie has a triangular-shaped card. The lengths of its sides are 2.7 cm, 3.6 cm, and 4.5 cm. Is the card a right triangle?​

Answer 1

`\sqrt{ {2.7}^(2) + {3.6}^(2) } = 4.5 \\\Rightarrow The \: card \: is \: a \: right \: triangle`

Answer 2

Yes it is the right angle triangle

Explanation:

In right angle triangle hypotenuse is equal to sum of perpendicular and base

(H) ^2 = P ^2 + B ^2

(4.5) ^2 = (2.7) ^2 +(3.6) ^2

20.25 = 7.29 +12.96

20.25 = 20.25

Hence, it is right angle triangle .
