Please help! :) 1. Explain the difference between a long-term goal and a short-term goal when writing a proof.(1 point)

A long-term goal when writing a proof would be to complete an indirect proof. A short-term goal would be to complete a direct proof.

A long-term goal when writing a proof would be to prove a statement. A short-term goal would be to apply a postulate or theorem that helps to prove the statement.

A short-term goal when writing a proof would be to complete an indirect proof. A long-term goal would be to complete a direct proof.

A short-term goal when writing a proof would be to prove a statement. A long-term goal would be to apply a postulate or theorem that helps prove the statement.

2. Justin and Amy are trying to prove the Triangle Angle Sum Theorem. Justin draws a triangle on a piece of paper, tears off the corners, and arranges them to form a line. Amy constructs a line through one vertex that is parallel to the opposite side and uses the Alternate Interior Angles Theorem to show that the interior angles add up to 180°. Who proved the theorem? Explain. (1 point)

Only Amy proved the theorem because she used postulates and theorems to construct a logical argument to show that the interior angles in a triangle add up to 180°.

Neither Amy nor Justin proved the theorem.

Only Justin proved the theorem because he demonstrated that the angles formed a line.

Both Amy and Justin proved the theorem. Amy used postulates and theorems, while Justin used a demonstration.

Will give brainliest!!
