Geometry Unit 2 Test

Identify the HYPOTHESES of:

"If an angle has a measure of 90 degrees that it is a right angle."

• If an angle has a measure of 90 degrees

• then it is a right angle

• an angle has a measure of 90 degrees

• it is a right angle

Identify the CONCLUSION of:

"If an angle has a measure of 90 degrees than it is a right angle."

• If an angle has a measure of 90 degrees

• then it is a right angle

• it is a right angle

• an angle has a measure of 90 degrees

Identify the CONVERSE of:

"If an angle has a measure of 90 degrees than it is a right angle."

• If an angle is a right angle then it has a measure of 90 degrees

• If an angle does not have a measure of 90 degrees then it is not a right angle

• If an angle is not a right angle than it does not have a measure of 90 degrees

• If and angle is a right angle then it does not have a measure of 90 degrees

Rewrite in IF-THEN form:

"A pentagon has 5 sides"

• If it has 5 sides then it is a pentagon.

• If it is a pentagon then it has 5 sides.

• If it is not a pentagon then it does not have 5 sides.

• A shape is a pentagon if and only if it has 5 sides.
