# Just two lines

Geometry Level 3

Line 1:- $$x+y=a$$ and

Line 2: - $$x/m+y/t=1$$ are two lines, $$a,m,t>0.$$

Area bounded by them are $$A1, A2, A3.$$

$$A1$$ : area between Y-axis, line 1 and line 2.

$$A2$$ : area between X-axis, line 1 and line 2

$$A3$$ : area between X-axis, Y-axis , line 1 and line 2

Which is always true?
