Question

Below are some lengths of sides are given to draw a triangle. Decide
whether triangles with sides of this length can be drawn. Write the
reason.
1) 17 cm, 7 cm, 8 cm
2) 7 cm, 24 cm, 25 cm
3) 9 cm, 5 cm, 16 cm​

Answer 1

Answer:

2) 7 cm, 24 cm ,25 cm

Step-by-step explanation:

Let the ∆ ABC be right angled at B.

angle B = 90°

AB= 24 cm , BC = 7 cm and AC = ?

By the Pytagoras Theorem:-

AC = √ AB^2 + BC^2

AC = √ (24)^2 + (7)^2

AC = √ 576 + 49

AC = √ 625

•°• AC = 25 cm
