3.) What is the y-intercept of an equation y=7x+8?
The triangles are congruent because △A′B′C′ is a rotation of △ABC, and a rotation is a rigid motion.
The triangles are congruent because △A′B′C′
is a reflection of △ABC, and a reflection is a rigid motion.
The triangles are not congruent because △A′B′C′
is a translation of △ABC, and a translation is not a rigid motion.
The triangles are not congruent because △A′B′C′
is a reflection of △ABC, and a reflection is not a rigid motion.
The correct option is :
(B)The triangle are congruent because the triangle A'B'C' is a reflection of triangle ABC and a reflection is a rigid motion.
Step-by-step explanation:
Given information:
The rule (x,y) going to (-x,y) maps triangle ABC to Triangle A'B'C'
Now,
The reflection is going on if we are going from (x,y) to (-x,y)
For example the point (1,3) will map (-1,3) , this is a reflection over y axis.
A reflection will keep the two points the same distance apart so we can say it will preserve the side length and distance.
Hence, if triangle ABC is reflected over y axis then A'B'C' is congruent to ABC.
So, The correct option is :
(B)The triangle are congruent because the triangle A'B'C' is a reflection of triangle ABC and a reflection is a rigid motion.
