All you have to do is draw two circles then make lines in the circles so that you have 8 pieces, do that twice.
1/2 = 0.5
4/6 =0.67
3/8=0.375
1/3=0.33
2/5=0.4
There fore 1/2 is bigger :)
Check the picture.
Note that reflecting triangle ABC with respect to the x-axis, and translating it 3 units down, mapps it perfectly to A'B'C'.
Thus, the answer is: <span>△ABC is congruent to △A′B′C′ because you can map
</span>
△ABC to △A′B′C′ using a reflection across the x-axis followed by a translation 3 units down, which is a sequence of rigid motions.
