Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.Which of the following happens when a shape is reflected by a line of reflection along the x-axis?

The shape is translated to the rightThe shape is translated to the leftThe reflected shape has the same x coordinate as the original shapeThe reflected shape has the same y coordinate as the original shape

Q2.If a shape is reflected by a line of reflection along the x axis then which of the following is correct?

Both the x and y coordinates of the reflected shapes must stay the sameBoth the x and y coordinates of the reflected shapes must changeThe x coordinate will definitely stay the sameThe y coordinate will definitely stay the same
