BRANLIEST WILL BE GIVEN
Figure ABCD is transformed to figure A′B′C′D′:


A coordinate grid is labeled from negative 5 to 0 to 5 on both x and y axes at increments of 1. Figure ABCD has A at ordered pair 1, 1, B at 3, 3, C at 4, 2, D at 4, 1. Figure A prime B prime C prime D prime has A prime at ordered pair 1, negative 3, B prime at 3, negative 1, C prime at 4, negative 2, D at 4, negative 3.


Which angle in figure A′B′C′D′ is equal to Angle BCD.?


Angle D prime A prime B prime.

Angle A prime B prime C prime.

Angle B prime C prime D prime.

Angle C prime D prime A prime.

Sagot :

Answer:

The correct is 4.

Step-by-step explanation:

It is given that figure ABCD is transformed to figure A′B′C′D′.

The vertices of ABCD are A(1,1), B(3,3), C(4,2) and D(4,1).

The vertices of A'B'C'D' are A'(1,-3), B'(3,-1), C'(4,-2) and D'(4,-3).

It is clear that the figure translate 4 units down and the rule of translation is

(x ,y) -->(x ,y - 4)
