Geometry proofs

How can you identify the midpoint of a segment?

• The midpoint is the point that is equidistant from both endpoints of the segment.

• The midpoint is the point that is closest to one endpoint of the segment.

• The midpoint is the point that divides the segment into three equal parts.

• The midpoint is the point that lies outside the segment.

What must be shown to prove that two angles are supplementary?

• Their measures add up to 90 degrees.

• Their measures add up to 180 degrees.

• Their measures are equal.

• Their measures add up to 360 degrees.

What is the measure of an angle?

• The distance between two points on a line.

• The amount of rotation needed to bring one ray into alignment with another ray, typically measured in degrees.

• The length of the longest side of a triangle.

• The sum of the interior angles of a polygon.

What is the relationship between a segment bisector and the midpoint?

• A segment bisector intersects the segment at its midpoint, creating two equal segments.

• A segment bisector is a line that divides the segment into three equal parts.

• A segment bisector is always perpendicular to the segment it bisects.

• A segment bisector can only exist in three-dimensional space.

What is a segment bisector?

• A point that divides a segment into two unequal parts.

• A line that intersects a segment at its midpoint.

• A segment that connects two endpoints without dividing them.

• A point, line, ray, or segment that divides another segment into two equal parts.

What does it mean for two angles to be supplementary?

• Two angles are supplementary if the sum of their measures is 180 degrees.

• Two angles are supplementary if they are both acute angles.

• Two angles are supplementary if they are both right angles.

• Two angles are supplementary if their measures add up to 90 degrees.

What can be concluded if two angles are supplementary?

• The sum of their measures equals 90 degrees.

• The sum of their measures equals 180 degrees.

• The sum of their measures equals 360 degrees.

• The sum of their measures equals 270 degrees.

What is the Segment Addition Postulate?

• The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

• The Segment Addition Postulate states that the sum of the lengths of two segments is equal to the length of the longest segment.

• The Segment Addition Postulate states that if two segments are equal, then their lengths are the same.

• The Segment Addition Postulate states that the length of a segment is always greater than zero.

What is the definition of a midpoint?

• A point that divides a segment into two equal segments.

• A point that marks the end of a segment.

• A point that is equidistant from the endpoints of a segment.

• A point that connects two segments.

What is a proof in geometry?

• A method of drawing geometric shapes accurately.

• A logical argument that uses definitions, properties, and previously proven statements to demonstrate the truth of a geometric statement.

• A technique for measuring angles and distances in geometric figures.

• A set of rules for constructing geometric figures.
