For 99 pts and brainliest the vertices of kite defg are (5, 5), (8, 2), (5, -4), and (2, 2), respectively. prove that the diagonals of kite defg are perpendicular lines.

See below

Step-by-step explanation:

Vector argument

Vector DF is (5, -4) - (5, 5) = (0, -9).

Vector EG is (2, 2) - (8, 2) = (-6, 0).

The dot-product of these two vector is (0, -9)•(-6, 0) = 0·(-6) + (-9)·0 = 0.

When the dot-product of two vectors is zero, those vectors are at right-angles to each other. Therefore diagaonal DF ⊥ diagonal EG.

Alternate argument

The x-coordinates of points D and F are the same, so diagonal DF is a vertical line. The y-coordinates of points E and G are the same, so diagonal EG is a horizontal line. Vertical lines are perpendicular to horizontal lines, so DF ⊥ EG.

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.
