kite is a quadrilateral with two pairs of adjacent, congruent sides. The vertex angles are those angles in between the pairs of

just olya [345]

If we have a kite ABCD where AB = CD and DC = CA.
Let E be a midpoint between BC
Since triangle ABC is an isosceles triangle, ray BE bisects angle ABC and is perpendicular to AC.
So, angle ABE = CBE.
<span>Since also triangle CDA is isosceles, line DE is perpendicular to AC for the same reason. Therefore, AC is perpendicular to BD.</span>

A full glass of water can hold 1/6 of a bottle.

uysha [10]

Answer:

21 glasses of water.

Step-by-step explanation:

You can do a proportion.

$\fraction{1 glass}{1/6 of a bottle)$ or

1 glass/1/6 of a bottle.

x glasses/3.5 bottles.

You can cross multiply.

1/6 times x is 1/6x

1 times 3.5 is 3.5/

1/6x=3.5.

do the reciprocal of 1/6 which is 6.

So, 6 times 3.5 is 21.

Therefore, you have 21 glasses of water.
