Question

triangle ABC is reflected over the Y axis. what are the coordinates of the reflected triangle

Answer 1

Answer:

A'(-1,3),B'(-4,5),C'(-3,1).

Step-by-step explanation:

The coordinates of the vertex of the given triangle are A(1,3) ,B(4,5) ,C(3,1).

When a point is reflected along the y axis the y value f the point (x,y) remains the same while x changes its sign.

Point (x,y) will have the reflected pint x'(-x,y)

The reflected points along the y axis are:

A(1,3) ......A'.(-1,3)

B(4,5).......B'(-4,5)

C(3,1)........C'(-3,1)

Answer 2

The coordinates of the reflected triangle are;

• A'(-1, 3)
• B'(-4, 5)
• C'(-3, 1)

Reflection over a line

According to the given diagram;

The coordinates of the given triangle are;

• A(1, 3)

• B(4, 5)

• C(3, 1)

On this note, when the triangle is reflected over the y axis to give triangle, A'B'C';

The x-coordinate all change signs and the coordinates of the reflected triangle are;

• A'(-1, 3)
• B'(-4, 5)
• C'(-3, 1)
