Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
3+2+1/2+1/7
5+1/2+1/7
5+7/14+2/14
5+9/14
5 9/14
If both triangles ABE = CBD then <C = <A
Hope it helps.
