Question

if AB=7cm BC=15cm and AC=17cm then triangle ABC s right angle triangle is this true or false​

Answer 1

Answer:

false

Step-by-step explanation:

Answer 2

Solution :

Here it is given that

• AB = 7cm
• BC = 15cm
• AC = 17cm

We've to find whether it is a right angled triangle or not.

Steps :

As we know that

AC² = AB² + BC² [ Pythagoras theorem ]

Where

• AC = hypotenuse of the right angled triangle
• AB = perpendicular of the right angled triangle
• BC = base of the right angled triangle

• Now, according to question :

➟ (17)² = (7)² + (15)²

➟ 289 = 49 + 225

➟ 289 ≠ 274

Therefore, ∆ABC is not a right angled triangle.
