Question

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 3, 4, B at ordered pair negative 4, 2, C at ordered pair negative 1, 1. A triangle A prime B prime C prime has A prime at ordered pair 3, 4, B prime at ordered pair 4, 2, C prime at ordered pair 1, 1.

Which equation shows the correct relationship between the measures of the angles of the two triangles?

The measure of angle ABC = The measure of angle A prime B prime C prime

The measure of angle ABC = The measure of angle B prime C prime A

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

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

Answer 1

The answer above is right.

Answer 2

The measure of angle ABC = The measure of Angle A' B' C'

Explanation:

Because

<A = <A'

<B = <B'

<C = <C'
