How to find the perimeter of a right angle triangle with one side missing ?
A perimeter is defined as total length of a triangle around the shape.
Answer: Using pythagoras theorem, we can find other side and perimeter of triangle = a+b+c, if a,b and c are sides of triangle.
Find missing side and perimeter
Find missing side and perimeter if hypotenuse side is 5 units and base side is 4 units.
Using pythagoras theorem, if 'a' and 'b' are sides of a right angle triangle and 'c' is hypotenuse side
Then, c2 = a2 + b2
52 = 42 + b2
25 = 16 + b2
9 = b2
b = 3
The other side is 3 units
Now, perimeter of triangle = a+b+c
P = 3 + 4 + 5
P = 12
Perimeter = 12 units
