Figure PQRS is reflected about the y-axis to obtain figure P'Q'R'S':

A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A polygon PQRS has P at ordered pair 1, 1, Q at ordered pair 2, 3, R at ordered pair 3, 3, S at ordered pair 4, 2. A polygon P prime Q prime R prime S prime has P prime at ordered pair negative 1, 1, Q prime at ordered pair negative 2, 3, R prime at ordered pair negative 3, 3, and S prime at ordered pair negative 4, 2.

Which statement best describes the relationship between the two figures?

Figure PQRS is bigger than figure P'Q'R'S'.
Figure PQRS is similar to figure P'Q'R'S'.
The measure of angle S is equal to the measure of angle Q'.
The measure of angle S is equal to the measure of angle P'.

Triangle ABC is transformed to triangle A′B′C′, as shown below:


A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Which equation shows the correct relationship between the measures of the angles of the two triangles?

The measure of angle CAB = The measure of angle C prime B prime A prime
The measure of angle BCA = The measure of angle A prime B prime C
The measure of angle CAB = The measure of angle C prime A prime B prime
The measure of angle BCA = The measure of angle C prime A prime B prime
