Liam and Tehya are trying to determine whether ΔABC and ΔEFD can be proven congruent through rigid motions. Liam says that ΔABC
≅ ΔEFD because ΔABC can be reflected over the y-axis to create ΔEFD. Tehya says that ΔABC ≅ ΔEFD because ΔABC can be rotated 90° clockwise about the origin to create ΔEFD. a coordinate grid with triangles ABC and DEF at A at negative 7 comma 2, B at negative 3 comma 6, C at negative 2 comma 1, D at 2 comma 1, E at 3 comma 6, and F at 7 comma 2 Who is correct? Liam only Tehya only Both Liam and Tehya Neither Liam nor Tehya
when subtracting a positive integer from a negative, the answer becomes smaller. If the question were to ask -3-(-1) negative 3 minus negative 1, the subtraction sign becomes a addition sign, and you add 1 to -3.
