Question

The sides of certain triangles are given. Determine which of them is a
right-angled triangle.
a] 2.5cm, 6.5 cm,6cm b] 7cm,5.6 cm and 4.2cm.

Answer 1

Answer:

b] 7cm, 5.6cm and 4.2cm

because, right angled triangles have the phythagorean theorem

7^2 = 5.6^2 + 4.2^2

49 = 31.36 + 17.64

49 = 49

Answer 2

Step-by-step explanation:

Answer a. is right angle triangle

by

Pythagoras furmula put of right angle triangle

H^=B*+P^

(6.5)*=(2.5)+6*

42.25=6.25+36

42.25=42.25

so the above side of given triangle is right angle triangle
