Drawing Conclusions in Geometry

What is the first step in drawing conclusions according to Miss Lindsay?

• Justify the conclusion

• Draw a conclusion

• Memorize theorems, definitions, and postulates

• Identify key words and symbols

Why is it important to look for key words and symbols in the given information?

• To write a two-column proof

• To make the problem more interesting

• To identify the relevant theorems, definitions, or postulates

• To draw a diagram

In Example 1, what is the key symbol identified in the given information?

• Parallel

• Perpendicular

• Adjacent

• Congruent

What conclusion can be drawn from two perpendicular lines?

• They form an acute angle

• They form a right angle

• They form an obtuse angle

• They form a straight line

In Example 2, what does it mean if two angles are complementary?

• Their sum is 180 degrees

• Their sum is 90 degrees

• They are equal

• They are adjacent

What is the conclusion if two angles are complementary and adjacent?

• They form a right angle

• They form an obtuse angle

• They form a straight line

• They form an acute angle

In Example 3, what does it mean if two angles are congruent?

• They are adjacent

• They are equal in measure

• They are complementary

• They are supplementary

What is the conclusion if a segment bisects an angle?

• The angle is divided into two equal parts

• The angle is divided into three equal parts

• The angle is complementary

• The angle is supplementary

In Example 4, what does it mean if an angle is trisected?

• It is divided into two equal parts

• It is complementary

• It is divided into three equal parts

• It is supplementary

What is the conclusion if a segment bisects another segment?

• The segments are perpendicular

• The segments are divided into two equal parts

• The segments are parallel

• The segments are congruent
