Question

Paola translated trapezoid ABCD four units to the right and two units up. If angle A is 57 degrees ° and angle C is 123 degrees what is the degree measurement of angle C'?
1. 180

2. 123

3. 66

4. 57

Answer 1

Answer:

2. 123°

Step-by-step explanation:

The transformations applied are

i) Horizontal shift to the right by 4 units

ii) Vertical shift upward by 2 units

We know that the translations have no effect on the angle

Therefore,

the degree measure of angle C' is 123°

Answer 2

Answer:

Option 2

Step-by-step explanation:

Measurement of angles doesn't change after shapes are translated, this is one of the properties of translated angles.
