Write a two-column proof.
given: angle 12 and angle 11 are complementary.
measure of angle 10 + measure of angle 11 = 90 degrees.
prove: angle 12 is congruent to angle 10.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
