Focus Standards

NC.ECS.M1.G-GPE.5 Know the attributes of perpendicular lines, parallel lines, and line
segments Compare lines on the coordinate plane, to identify parallel lines and recognize
that parallel lines have the same slope (rate of change).

NC.ECS.M1.G-GPE.6 Use coordinates to find the midpoints or endpoints of a line
segment, in the first quadrant.

Vocabulary

An endpoint is at the end of a line.

A midpoint is in the middle of a line.

Intersecting lines go in different directions.

They do not make an L where they touch.

Vocabulary

Vocabulary

Parallel lines move in the same direction.
They do not touch each other and have

the same slope.

Perpendicular lines move in different directions.

They make an L where they touch.

Vocabulary

Can you make an L with your hand?

Repeated Storyline

Perpendicular lines make right angles,
parallel lines never touch, and
intersecting lines do not make right
angles

Using Endpoints to Find Midpoints

Midpoint Formula

First find the two
coordinate
endpoints.

(4,2) and (8,5)

Plug coordinates into
the midpoint
formula.

(x₁,y₁) and (x₂,y₂)
(4,2) and (8,5)
