Answer 1

A

Answer 2

A

Answer 3

a

Answer 4

Opposites angle are equal is true in a parallelogram
Adjacent angles are suplementary is also true in a parallelogram
And diagonals bisects each other are true in a a parallelogram

Answer 5

A?
I thought it was C... :/

Answer 6

noo :P.

Answer 7

diagonals bisect in square

Answer 8

apply triangle rules

Answer 9

what?

Answer 10

Answer 11

yeah B :)

Answer 12

yup

Answer 13

Thank you, thank you!

(This one I have no clue , how to do-I keep getting 11.)

Figure ABCD is a kite. The length of side AD is (4x + 7) inches, the length of side CD is (7x - 5) inches, and the length of side AB is 12 inches. The measure of Angle A is equal to the measure of angle C .


What is the length of side AD in inches?

A. 21

B. 23

C. 12

D. 16

Answer 14

c12

Answer 15

note in that figure opposite angles are equal , and they sum up to 360 ,
so D +C =180 so opposite sides are parallel , so its a parallelogram so opposite sides are equal , moreover its a kite so adjacent sides are equal , so all sides are equal =12

forgive me for the horrible drawing
