Geometric Constructions: Key Concepts and Techniques

What are the two tools allowed for geometric constructions?

• Compass and protractor

• Ruler and protractor

• Compass and straight edge

• Ruler and pencil

When using a ruler as a straight edge, what is not allowed?

• Drawing straight lines

• Measuring inches or centimeters

• Using it as a guide

• Drawing arcs

What is the first step in copying a line segment?

• Measuring the segment with a ruler

• Designating a point

• Drawing a circle

• Drawing an arc

How do you ensure the copied segment is the same length as the original?

• By drawing a parallel line

• By keeping the compass length unchanged

• By using a protractor

• By measuring with a ruler

What is the first step in copying an angle?

• Drawing a straight line

• Designating a vertex

• Measuring the angle with a protractor

• Drawing a circle

What do you call the points where the arc intersects the sides of the angle?

• Vertices

• X and Y

• Endpoints

• Intersections

What is the purpose of drawing a transversal when creating parallel lines?

• To mark the midpoint

• To draw a circle

• To measure the distance

• To create a reference angle

What type of angles are created when two parallel lines are cut by a transversal?

• Adjacent angles

• Corresponding angles

• Alternate interior angles

• Vertical angles

What is the final step in drawing parallel lines?

• Drawing a circle

• Drawing a transversal

• Connecting points with a straight edge

• Measuring the angles

What ensures that the lines drawn are parallel?

• Equal length of segments

• Congruent corresponding angles

• Equal distance between lines

• Same starting point
