The perimeter of an isosceles triangle is 71 centimeters. The measure of one of the sides is 22 centimeters. What are all the po
Paha777 [63]
An isosceles triangle has 2 sides the same length and 1 side of a different length
 

so if the 22 is the identical length then you would have another side of 22
 and the 3rd side would be 71 - 22 -22 = 27 cm
 so you could have 22 and 27

 if the 22 is the odd length side then you would have 71 - 22 = 49 / 2 = 24.5
so you could have 24.5 and 24.5
