Error analysis. find and correct all 3 of the errors in the proof.( 3 points)

The correct reason for is property of corresponding angles and the reason for is substitute and the third error is the forget the property that the sum of consecutive interior angles is 180.

Explanation:

It is given that m is parallel to n.

When  two parallel lines intersected by a transversal eight angles are produced as shown in the given figure, where m and n are parallel and l is the transversal line.

In this case corresponding angles are congruent. Example , etc.

So, by the property of corresponding angles.

because these are supplementary angles.

Substitute

So, the correct reason is substitution.

Hence proved

The third error is the forget the property that the sum of one side interior angles is 180. Since the alternate interior angles are congruent therefore the consecutive interior angles are supplementary angles around the sum of consecutive interior angles is 180 degree.

Step-by-step explanation:

When you are adding something, it is positive. So you would have 1. You wouldn't put it as +1, just put it as 1.
