Question

Sides of triangle
are 20, 16, 12. Determine if it is
right angled triangle​

Answer 1

Step-by-step explanation:

Yes, a right triangle obeys the Pythagorean Theorem .

$[math]c^2 = a^2 + b^2 [/math]where[math] c > a [/math]and [math]c > b[/math]</p><p></p><p>[math]20 [/math]cm [math]= \sqrt{12^2 + 16^2}[/math] cm.$

As pointed out in the comments, I didn’t bother to calculate the math correctly. The numbers do work out, and it is a right Triangle

Answer 2

Answer:

It is a right angled triangle

Step-by-step explanation:

In a right angled triangle, the square of hypotenuse should be equal to the sum of the square of perpendicular and base ( Pythagoras theorem)

Applying that we get,

(20)^2 = (16)^2 + (12)^2

400 = 256 + 144

400 = 400

Since, the square of hypotenuse is equal to the sum of the square of perpendicular and base, it is a right angled triangle
