Identify: intersecting lines, perpendicular lines, andparallel lines on the shapes.

Answer:1. On Shape 7, how do you know that line segment

BC and line segment ED are not parallel?2. Does Shape 10 have a pair of perpendicular line

segments and?

Discuss:1. Can two lines be both intersecting lines and

perpendicular lines?2. Can two lines be both perpendicular and parallel

to each other?

3. Why is it important to think about a line segmentas being part of a line that extends forever inboth directions?

4. How can you monitor whether you haveaccurately identified relationships between linesegments?

IDENTIFYANDDRAWPERPENDICULARANDPARALLELLINESEGMENTS

Virtual Geoboard

Create a variety of quadrilaterals on yourboard to share with the class.

Discuss: Which shapes contain examples ofparallel and perpendicular line segments?

Create quadrilaterals with the followingattributes, and record shape drawingson Geoboard Dot Paper:

two pairs of parallel sides

one pair of parallel sides

one pair of perpendicular sides

Using the pattern blocks, find shapes with examplesof parallel and perpendicular line segments.

Answer: Which pattern blocks have sides that are parallel?

Which pattern blocks are parallelograms and why? Which pattern blocks have sides that are perpendicular

and why?

Are there any pattern blocks that do not containparallel or perpendicular lines?

Discuss the presence of parallel and perpendicularsides in other familiar shapes.

Answer: How does thinking about the properties ofshapes help you identify perpendicular and parallelline segments?

IDENTIFYANDDRAWLINESOFSYMMETRY

Visualize what will happen when a square isfolded in half.

Identify the lines of symmetryof this square.

Answer: How do you know you have identified all the lines

of symmetry on the square?

Do all quadrilaterals have lines of symmetry?


6/12


Cut out the shapes after identifying the lines of symmetry inorder to verify whether their predictions are accurate.


7/12


Answer:

What did you notice about the first figure?

What is different about the two pentagons?

How does folding help you verify your predictionabout a figures line of symmetry?


8/12



9/12


Using your pattern blocks, identify:

a shape with one line of symmetry

a shape with two lines of symmetry

a shape with more than two lines of symmetry

a shape with no lines of symmetry

Justify your selections.

Angles and Angle Measurements

Angles and Angle MeasurementsNotes

Create various angles based on angle

categories (for example - acute, obtuse,straight, right).

Record and label the measures of your angleson Geoboard Dot Paper using a straightedge.
