Answer:
See explanation below
Step-by-step explanation:
Can 4 cm, 5 cm and 6 cm be the sides of a right triangle?Justify.
For the side of the triangle to be right angled, the sum of the longest side must be equal to the sum of the squareof the other two sides
Given the sides 4cm, 5cm and 6cm
Longest side = 6cm
Square of longest side =6² =36cm
Sum of the square of other two sides = 4²+5²
= 16+25
= 41
Since 36≠41, hence the sides does not form a right angle.
