Question

do sides 7 cm 24cm 25cm from a right angled triangle give reason​

Answer 1

Answer:

Step-by-step explanation:

Yes they do.

A formula was made by pythagoras called pythagorean theorem which showed the relationship of sides of a triangle. It is a²+b²=h² where h is the hypotenuse or longer side of right angled triangle and a and b are the sides. This formula ONLY works for right angled triangles.

By this we can say that sides of all right angles follow this relationship.

Similarly we can also say that THE TRIANGLES WHOSE SIDES FOLLOW THIS RELATIONSHIP (pythagorean theorem) IS A RIGHT ANĢLED TRIANGLE which is exactly what is proven in your note in the picture.

Answer 2

Answer:

Yes this is write angle triangle

Step-by-step explanation:

$by \: the \: pythagoras \: theorem \: we \: have. \\ \\ (ac) {}^{2} = (ab) { }^{2} + (bc) {}^{2} \\ (25) {}^{2} = (24) {}^{2} + (7) {}^{2} \\ 625 = 576 + 49 \\ 625 = 625 \\ l.h.s = r.h.s \\ hence \: angle \: is \: right \: angle \: traingle.$
