Answer 1

Answer:

$\boxed{\textsf{ \textbf{ Yes} , the given triangle is a right angled triangle .}}$

Step-by-step explanation:

We are given three sides of the triangle and we need to say that whether the triangle is right Angled triangle or not . The given side lenghts are 6 cm , 8 cm and 10 cm . ( Units not given in Question ) .

$\textsf{ \implies Sides = 6cm , 8cm and 10 cm .}$

So , a triangle with its given sides will be a right angled triangle if it has a right angle . And the sum of squares of two smallest sides must be equal to the square of the longest side . ( According to Pythagoras Theorem ) .

Here two smallest sides are 8cm and 6cm .

$\implies\textsf{ \sf Sides_{(smallest)} = 8cm and 6 cm }$

And the largest side is 10 cm .

$\sf\implies Side_{(largest)}= 10 cm$

And here the sum of squares of 8cm and 6cm should be equal to the square of 10cm in order to Prove it a right angled triangle .

$\sf\implies (8cm)^2+(6cm)^2 = (10cm)^2 \\\\\sf\implies 64 cm^2+36cm^2 = 100 cm^2 \\\\\sf\implies \boxed{\pink{\frak{ 100 cm^2=100cm^2}}}$

Since LHS = RHS hence the triangle is a right angled triangle .

Answer 2

answer:

yes, it is a right triangle

step-by-step explanation:

• remember: a triangle can only be a right triangle if it works with the pythagorean theorem
• therefore, we can plug in the numbers we have in the formula
• know the formula: a^2 + b^2 = c^2
• now, plug in

a^2 + b^2 = c^2

6^2 + 8^2 = 10^2

• the largest side is always the hypotenuse
• we have to see if both sides equal to the same value

6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

• yes they are equal, therefore it is a right triangle
