Unit 2 Constructions & Measuring Angles

What is the measurement of this angle?

• 5 degrees

• 50 degrees

• 55 degrees

• 130 degrees

What is the FINAL step of constructing an angle bisector?

• Place your compass on each intersection point of both arc and sides of angle and then use your compass to construct two intersecting arcs inside the angle.

• Swing an arc through both sides of the angle.

• Draw a ray from vertex through intersection points of both arcs.

• Draw a ray from vertex through intersection points and then write a congruent statement for the two congruent angles.

What is the FIRST step when constructing a perpendicular bisector?

• Given a segment

• Open compass witdth more than half the length of segment

• place compass point on endpoint and wing an arc

• use a ruler to draw a line through intersecton of arcs

What is the FIRST step for Copying Angle ABC?

• Extend a Ray from point B

• Place compass point on given vertex and swing an arc through the sides of the angle. Move compass over to point B and swing an arc, label intersection point C

• Adjust the width of the compass to measure given angle. Place compass on point C and swing an arc crossing the two arcs label the intersection point A.

• Draw Ray BA through point A copying Angle ABC.

What is the FIRST step for constructing an equilateral triangle?

• Draw segement AB

• Draw Circle A, Center A, Radius AB. Draw Circle B, Center B, Radius BA.

• Place Point C on the intersection of Circle A and Circle B

• Draw Segment AC. Draw Segment CB.
