Question

Triangle A is reflected in the x axis to give triangle B, which is then reflected in the line y=x to give Triangle C. Draw Triangle C.

Answer 1

Answer:

The coordinates of triangle C on the grid are

(-5,4) , (-2,2) and (-2,4)

Step-by-step explanation:

We can identify the coordinates of the vertices of the triangles so as to get a diagram

For the first triangle, we have the following coordinates;

(4,5) , (2,2) and (4,2)

Now, let us get the coordinates of triangle B after reflecting triangle A in the x-axis

what we have in this case is that the x-axis coordinates stays same while the y-axis values are negated

Hence, the coordinates of triangle B are;

(4,-5) , (2,-2) and (4,-2)

Lastly we are to reflect triangle B in the line y = x so we get triangle C

A reflection over the line y= x means that we are going to switch the place of the x and y coordinates of the pre-image

So, the coordinates of triangle C are;

(-5,4) , (-2,2) and (-2,4)

Answer 2

The coordinates of triangle C are  (-5,4) , (-2,2) and (-2,4)

From the given image the vertices of the triangles are

Triangle A has coordinates (4,5) , (2,2) and (4,2)

After reflecting triangle A in the x-axis, triangle B is obtained  

On reflection in x-axis, the x-axis coordinates remain same while the y-axis coordinates become negative with the same magnitude.

Hence, the coordinates of triangle B are (4,-5),(2,-2) and (4,-2)

Now as triangle B is reflected by the line y = x to get triangle C,  the x and y coordinates of triangle B are interchanged.

So, the coordinates of triangle C are (-5,4),(-2,2) and (-2,4)
