If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm

With 3cm for each sides.

Its P= A+B+c where A, B and C are the sides of the triangle and P = the perimeterexampleside a=12cm, side b=12cm and side c= 20cmtherefore 12+12+20 = (P) 44cm (centimetres)

12cm (4 sides x 3 = 12)

Isosceles
