Triangle pqr has coordinates p (0, 0), q (-4,0), and r (0, 2). if apqr - axyz, what is the measure of xy?
1 units
2 units
3 units
4 units

4 units

Step-by-step explanation:

Since the two triangles are similar, their sides are proportional. To find the length of the side, you need to use the distance formula:

The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:

Then, simplify everything under the radical:

Finally, take the square root of 16:

= 4
