Points X, Y, and Z are on the sides QR , PR, and PQ respectively, of right triangle PQR such that PZXY is a square. If PQ=10 and PR=10, then what is the side length of the square?

Since PZXY is a square, we know that QZ = QX and RY = RX. Let's call the side length of the square s. Then, we have:

QZ + RY = PQ - s (since QZ and RY are on the sides PQ and PR, respectively)
QX + RX = QR - s (since QX and RX are on the side QR)

But we know that PQ = 10 and PR = 10, so PQ - s = PR - s = 10 - s. Therefore:

QZ + RY = 10 - s
QX + RX = QR - s

We also know that QZ + QX = QP and RY + RX = RP, so:

QP + RP = QZ + QX + RY + RX = (QZ + RY) + (QX + RX) = (10 - s) + (QR - s)

But we also know that PQ^2 + PR^2 = QR^2 (since PQR is a right triangle), so:

10^2 + 10^2 = QR^2
QR = sqrt(200) = 10sqrt(2)

Substituting this into the equation above, we have:

QP + RP = (10 - s) + (10sqrt(2) - s)

Since QP + RP = PQ + PR = 20, we can solve for s:

20 = (10 - s) + (10sqrt(2) - s)
20 = 20sqrt(2) - 2s
2s = 20sqrt(2) - 20
s = 10sqrt(2) - 10

Therefore, the side length of the square is s = 10sqrt(2) - 10.

To find the side length of the square PZXY, we can use the information given about the sides of triangle PQR.

Given that PQ = 10, PR = 10, and PZXY is a square, it implies that XZ = YZ (as opposite sides of a square are equal).

Since PR = 10, we can deduce that QR = PQ - PR = 10 - 10 = 0. This means that triangle PQR is degenerate and essentially a line segment.

Since triangle PQR is degenerate, we know that points X, Y, and Z must all coincide with point P, making triangle PXY degenerate as well.

Therefore, the side length of square PZXY is equal to the length of side PQ, which is 10 units. So, the side length of the square is 10 units.

To find the side length of the square PZXY, we need to determine the relationship between the sides of the right triangle PQR and the square. Let's break down the problem step by step.

Given that PZXY is a square, we know that all its sides have the same length. Let's assume the side length of the square is s.

Since XY is a side of the square and is parallel to QR, it divides QR into two segments, PX and RY. The combined length of PX and RY is equal to 10 (PQ). Therefore, PX + RY = 10.

Similarly, since ZY is a side of the square and is parallel to PR, it divides PR into two segments, PZ and ZR. The combined length of PZ and ZR is equal to 10 (PR). Therefore, PZ + ZR = 10.

Now, we can use these equations to find the side length of the square.

From the first equation PX + RY = 10, we can substitute PX = s and RY = 10 - s (since PX and RY are segments of QR) to get s + (10 - s) = 10.

This simplifies to s + 10 - s = 10, which further simplifies to 10 = 10.

Since the equation is true, we can conclude that any value of s satisfies the equation. In other words, the side length of the square can be any value.

Therefore, without any further information or constraints, we cannot determine the exact side length of the square PZXY.
