Question 1 options:
True
False
Question 2 (1 point)
To map triangle ABC onto triangle A'B'C', dilate triangle ABC from the origin by what scale factor?
ow can we tranlsate our red triangle in a sequence to prove triangle ABC is similar to triangle A'B'C'?
Question 3 options:
Translate the red triangle 2 units to the left and 5 units up.
Translate the red triangle 5 units to the right and 2 units down.
Translate the red trianlge 5 units to the right and 2 units up.
Translate the red triangle 2 units to the right and up 5 units.
Question 2 options:
r = 2
After the translation, what is the next transformation to map the red triangle onto triangle A'B'C' to prove triangle ABC and triangle A'B'C' are similar?

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
