Hey, i'm dumb and need . prove that opposite sides of a parallelogram are congruent. be sure to create and name the appropriate geometric figures. (10 points) (the blanks below need to be filled in) let abcd be a parallelogram. by definition of a side ab is parallel to side cd and side bc is parallel to side da. construct diagonal bd using a straightedge. ∡abd is congruent to ∡bdc by thetheorem. by the same theorem, ∡cbd is congruent to ∡adb. segment bd is congruent to itself by the property of equality. therefore, abd is congruent to cdb by and opposite sides of parallelogram abcd are congruent by ye kindly.

Parallelogram.

Alternate Interior angle.

Reflexive.

ASA

Step-by-step explanation:

AS for the last part i've only seen it in the States. Its something like CBCDC.

Basically it means the sides are congruent because  they are corresponding sides of 2 congruent triangles.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
