Module 6 lesson 14

I can construct parallel line segments and see and
analyze the relationship of the coordinate pairs.

Concept Development

Materials: (T) coordinate plane (Template), triangle 𝑅ST (created from
Lesson 13 Template 1) (S) Personal white board

Problem 1: Slide a right triangle template parallel to the
𝒙𝒙-axis along the coordinate plane to create parallel
segments.

(follow step-by-step instructions
from teacher guide)

Concept Development

Problem 2: Slide a right triangle template two directions
along a coordinate plane to create parallel segments.

(follow step-by-step instructions
from the teacher guide)

Concept Development

Problem 3: Identify coordinate pairs that create parallel
lines.

(follow step-by-step instructions
from the teacher guide)

​plot the following points. (Write C (1 1/2 , 2 1/2 ) and D (3, 2) on the board.)

​Focus for a moment on the vertex of the triangle that is at point C. Now,visualize that triangle moving 2 grid units to the left.

​Tell your neighbor

the location of that vertex now.

Drag and Drop

What is the

the location of that vertex now?

​Focus for a moment on the vertex of the triangle that is at point C. Now,visualize that triangle moving 2 grid units to the left.

​Plot it.

​Plot a point, E, at that location.

Plot another point, F, on the plane, that when connected to E will create a segment

parallel to CD̅̅̅̅.

Tell your neighbor how you will identify the

location of point F.

Plot point F, and then draw ̅EF̅̅̅ on your plane.
