Warm Up – If you have a laptop Connect to the S-drive and copy this powerpoint to your desktop. My Computer – KL-student (S:) – Teachers – S-T-U – Sturtevant_M – Outbox – Geometry_1.6.PPTX

Warm Up – Without a Laptop Everyone else, take out 2 pieces of paper and with each piece, fold once width-wise and once length-wise, then draw lines in the creases on front and back. Then, one person per table needs to come up and get a protractor and a compass for today’s activity.

Chapter 1.6 Construction Target: To make basic constructions using a straightedge and a compass

Definitions Construction – Use a straight edge and a compass to make geometric figures Straightedge – is a ruler with no marking on it Compass – Geometric tool used to draw circles and parts of circles called arcs Perpendicular Lines-two lines that intersect to form right angles. Perpendicular bisector-of a segment is a line that is perpendicular to the midpoint

Congruent segment

Set up for the Activity Front of PaperBack of Paper Draw a line segment Draw an acute angle Draw a line segment Draw 3 line segments of similar length Draw an angle slightly larger than 90º

Congruent Angles

Perpendicular Bisector

Angle Bisector

Construct a triangle given three line segments

Assignment #5 There is no assignment for tonight, simply turn in your activity from today into the folders. Be sure to label it with your name.
