Hi Austin!
The congruent sides of an isosceles triangle are each 1 unit longer than the length of the shortest side of the triangle. The perimeter of the triangle is the same as the perimeter of a square whose side length is 2 units shorter than the length of the shortest side of the triangle. What is the length of the shortest side of the triangle?
We Know:
Isosceles Triangle is a triangle with sides with the same length and the other not.
x = both equal sides
y = smaller side
x is 1 unit longer than y
Same perimeter as a square that the length is 2 units shorter than the shortest side.
Solution:
Use 10 (y = 10)
Triangle: 10 + 10 + 9 = 29
Square: 7 + 7 + 7 + 7 = 28
Answer - 10 units
Hope This Helps :)
