Can someone help me with number 4
2 answers:
4. The triangles are similar because the corresponding sides are in the same proportion.
21/15 = 7/5 = 11.2/8
They are similar!
21 ÷ 15 = 1.4
5 x 1.4 = 7
8 x 1.4 = 11.2
Since the scale factor for the enlargement of all of the sides is the same, the triangles are mathematically similar!
