Law of Syllogism

[annad95]

Use the Law of Syllogism to draw a conclusion from the given information.
Given: If two lines meet at a 90 degree angle, then they are perpendicular. If two lines are perpendicular, then they
form right angles. Two lines meet at a 90 degree angle.

What have you thought about so far, in this exercise?

 

[annad95]

Then they are perpendicular.

Then they are perpendicular.

I think that it might be an excellent idea to read what your textbook has to say about the Law of Syllogism. There should be a general pattern which looks something like this:

If p, then q.
If q, then r.
p
Therefore, r

There will also be at least one (and probably more) example which illustrates the law of syllogism; study the example(s) to see how that pattern has been applied. THEN see if you can apply it to your problem.

One seldom gets a correct answer by making wild guesses.
