Show that in a quadrilateral ABCD, AB+BC+CD+DA<2(BD+AC)

Snezhnost [94]

Step-by-step explanation:

We know that the length of the diagonals will be more than the side.

Lets suppose the quadrilateral is a rectangle, with sides 6 and 4.

The length of a diagonal is:

√(6*6)+(4*4)

√36+16

√52

7.21(rounded off to 3 sig. fig.)

So, 6+4+6+4<2(7.21+7.21)

20< 2*14.42

20<28.84, which is true.

Find the coordinates of the midpoint of line AB given the coordinates: A(-1,<br> 5) B(2,-3)*<br>

Naily [24]

Answer:

$\bold{M_{AB}\left(\frac12\,,\ 1\right)}$

Step-by-step explanation:

The midpoint of AB coordinates are: $M_{AB}\left(x_M\,,\ y_M\right)$ where:

$x_M=\frac{x_A+x_B}2=\frac{-1+2}2=\frac12\\\\y_M=\frac{y_A+y_B}2=\frac{5+(-3)}2=\frac{2}2=1$
