NO LINKS!!! 1. What is the structure of a proof in geometry?

2. Is ray AB the same as ray BA?

3. What is the difference between the m<A(measure of angle A) and <A (angle A)?

1.Geometric proofs can be written in one of two ways: two columns, or a paragraph. A paragraph proof is only a two-column proof written in sentences. ... A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true.

2.ray AB is not same as ray BA as ray AB has the starting point A and ray BA has B as the starting point.

3.∠ABC  refers to an angle, a geometric object.

m∠ABC  refers to the measure of  ∠ABC  which is a real number describing how “open” the angle is.

Step-by-step explanation:

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
