Use the Pythagorean theorem to prove if a triangle with side lengths 7,14,28 is a right triangle

Answer 1

No

Explanation:

Drawing a picture first will help. The hypotenuse, or the side opposite of the right angle, is the largest side, making 28 the hypotenuse. The other two remaining sides are the legs.

1. Start by filling out the formula A and B being the legs and C being the hypotenuse.

`7^(2)+14^(2)=28^(2)`

2. Simplify

49+196=784

`245\\eq784`

Answer 2

Taking 28 as the hypotenuse

If √ 7 ² + 14² = 28 then it's a right angled triangle

√7² + 14² = √ 49 + 196

= √ 245

= 7√5

Since it's not equal to 28 the lengths

7 , 14 , 28 is not a right angled triangle.
