Given:
abcd is

prove:
a = c

which of the following statements must be included in this proof?

triangle abd congruent to triangle cdb
triangle abc congruent to triangle cda
angle b congruent to angle d

Step-by-step explanation:

Given: ABCD is a parallelogram.

To prove: ∠A=∠C

Solution:

It is given that ABCd is a parallelogram, then

From ΔABD and ΔCDB, we have

AB=CD(Opposite sides of parallelogram are equal)

AD=CB (Opposite sides of parallelogram are equal)

BD=BD (Common)

Thus, by SSS rule of congruency,

ΔABD≅ΔCDB

Therefore, by CPCTC, we have

∠A=∠C

Hence proved.

the answer is 62

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
