Question

Use the premises and conclusion to answer the questions.

Answer 1

Answer: The argument is valid by the law of syllogism.

Step-by-step explanation:

Law of syllogism in geometric arguments is similar to transitive property  which tells that that if x=y and y=z then x=z.

Given premises: If the sides of a triangle are the same length, then the triangle is an equilateral triangle.  

If a triangle is an equilateral triangle, then the measure of each angle is 60°.  

Therefore by law of syllogism we can conclude that "If the sides of a triangle are the same length, then the measure of each angle is 60°."  

Answer 2

This  one is  choice C again.
