Answer:
#5
Ratio of corresponding sides of ΔACE and ΔBCD:
- AC/BC = 15/10 = 1.5
- EC/DC = 12/8 = 1.5
The triangles have similar sides and common included angle C.
#6
Let's verify if the sides (from the least to greatest length) have same ratio:
- EG/ML = 10/15 = 2/3
- FG/LN = 14/21 = 2/3
- EF/MN = 18/27 = 2/3
The ratios are same, it means:
