Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR= 5 m and diagonal QS
svet-max [94.6K]

Answer:

Given the statement: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P.

Properties of Kite:

  • The diagonals are perpendicular
  • Two disjoint pairs of consecutive sides are congruent by definition of kite
  • One diagonal  is the perpendicular bisector to the other diagonal.

It is given that: Side QR = 5m and diagonal QS = 6m.

Then, by properties of kite:

QP = \frac{1}{2}QS

Substitute the value of QS we get QP;

QP = \frac{1}{2}(6) = 3 m

Now, in right angle \triangle RPQ

Using Pythagoras theorem:

QR^2= RP^2 +QP^2

Substitute the given values we get;

(5)^2= RP^2 +(3)^2

or

25= RP^2 +9

Subtract 9 from both sides we get;

16= RP^2

Simplify:

RP = \sqrt{16} = 4 m

Therefore, the length of segment RP is, 4m
