MGSE6.G.3 Polygons in the Coordinate Plane

Poll

Based on the Squidward scale, how was you break?

​Standard: MGSE6.G.3

Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

Unit 8 Vocabulary

• Polygon- a closed figure with at least 3 sides, where all sides are straight (no curves)

• Two-dimensional figure –  a figure with two basic units of measure, usually length and width 

• Attributes of two-dimensional figures –  characteristics that define a geometric figure (e.g., sides, vertices, etc.)

Multiple Choice

What is a Cartesian Coordinate Plane?

• A graph.

• An x and y axis with an origin.

• A place to draw lines.

• In Mathematics, the cartesian plane is defined as a two-dimensional coordinate plane, which is formed by the intersection of the x-axis and y-axis. The x-axis and y-axis intersect perpendicular to each other at the point called the origin.

Multiple Choice

The vertical axis is called the:

• Up and down line

• x axis

• y axis

• answer not shown.

Multiple Select

The origin is (select all that apply).

• A location on a coordinate plane.

• A coordinate.

• (0, 0)

• Where the axes intersect (cross).

Multiple Select

What is a coordinate?

• A location on the map.

• (x, y)

• You can think of it like an address.

• a graph.
