Answer:
Step-by-step explanation:
In retail grocery stores in the US, you can find ice cream packaged in sizes of 1 cup (half pint), 1 pint, 1 quart, 1/2 gallon, 1 gallon, and perhaps some odd sizes in between. For commercial purposes, ice cream may be packaged in tubs of 3- or 5-gallons or more.
1 teaspoon would be an unusually small size, and 1 mL is about 1/5 of a teaspoon. These quantities are somewhat smaller than would be considered a "serving" of ice cream, so would generally be of little practical use.
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have

and the modulus would simply be

. Since

we would expect the final product to fall in the first quadrant.
The corresponding parts that are congruent are (a) AB and DE
<h3>How to determine the congruent parts?</h3>
The statement ΔABC ≅ ΔDEF means that the triangles ABC and DEF are congruent.
This implies that the following points are corresponding points:
A and D; B and E; C and F
When two corresponding points are joined together, the congruent parts are:
AB and DE, AC and DF, BC and EF
Hence, the corresponding parts that are congruent are (a) AB and DE
