Question

4)The sides of a triangle measure 15 cm, 36 cm and 39 cm. Show that it is a right-angled triangle.

Answer 1

Answer:

The right angle triangle follow the Pythagorean triplet.

H^2=P^2+B^2H

2

=P

2

+B

2

Where, H is the hypotenuse the longest side

So, H=39 cm

P is the perpendicular

Let P=36 cm

B is the base

B=15 cm

Substitute the values if they are equal then it form a right angle triangle.

39^2=36^2+15^239

2

=36

2

+15

1521=1296+2251521=1296+225

1521=15211521=1521

As LHS=RHS

Answer 2

Answer:

yes it is a right angle triangle

Step-by-step explanation:

if it is a right angle triangle then it follow Pythagoras Rule

The longest side in right triangle is the Hypotenuse

Acc. to Pythagoras theorem

H²= P²+B²

39²= 36²+15²

1521=1296+225

1521= 1521

it satisfies therefore it is a right triangle
