If it is a holiday, then we do not have school. Conjecture: Today is not a holiday, therefore we do not have school. Is the conjecture true or false? If false, provide a counterexample. 2. Which law are you using above? 3. Make a valid conclusion using the sentences below: If two angles have the same measure, then they are congruent. If two angles are congruent, then they are the same size and shape. Therefore: 4. Which law are you using above?

  2. Exploration:

  3. Exploration: If a triangle has two congruent angles then it is called isosceles. In triangle ABC, m<A = 80 degrees. In triangle ABC, m<B = 50 degrees. If a triangle is called isosceles then it has two congruent sides. Conclusion: Triangle ABC has two congruent sides. Use the information above to prove and convince me if this conclusion is true or not true. You may re-write (and re-order) the sentences and supplement the sentences with any other work, or visuals as explanation.
