PSA2RA8 - Classwork---Geometry, M1, Lesson 16 (G.CO.A.2, G.CO.A.4, G.CO.A.5)

In lesson 4, you completed a construction exercise that resulted in a pair of parallel lines (Problem 1 from the Problem Set). Now we examine an alternate construction.

Construct the line parallel to a given line AB through a given point P.

1. Draw circle P: Center P, radius AB.

2. Draw circle B: Center B, radius AP.

3. Label the intersection of circle P and circle B as Q.

4. Draw PQ.

Note: Circles and B intersect in two locations. Pick the intersection Q so that points and Q are in opposite half-planes of line PB.

Part A)

Draw the vector that defines each translation below

a)

Finding the vector is relatively straightforward. Applying a vector to translate a figure is more challenging. To translate a figure, we must construct parallel lines to the vector through the vertices of the original figure and then find the points on those parallel lines that are the same direction and distance away as given by the vector.

c)

Use your compass and straightedge to apply 𝑇 𝐴𝐵 to segment 𝑃1𝑃2 . Note: Use the steps from the Exploratory Challenge twice for this question, creating two lines parallel to 𝐴𝐵 : one through 𝑃1 and one through 𝑃2 .
