A vertex is the point where two or more line segments meet. The plural is vertices.

Complete polygons with missing coordinates

Maths

In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations. In the future unit pupils will describe positions in all four quadrants drawing and translating simple shapes and reflecting them in the axes.

In the prior unit pupils rotated two lines around a fixed point to make different sized angles. They identified vertices. In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations.

Coordinates

Somewhere in the middle of the rectangle.

You have three vertices of a rectangle: A, B, and C. Where should vertex D be?

Lucas wants to find the coordinates of the missing vertices to complete the square. Which coordinates complete the square? 

Sofia wants to create a pentagon. She uses a dot to plot the final vertex. Which coordinates could it not be? 

Sofia completes a rectangle by plotting points C and D. Is she correct?

Sofia has plotted the final two vertices of a quadrilateral. She thinks that it’s a rectangle. Is Sofia correct?

Lucas plots another coordinate to complete a trapezium. He say he will plot it at (1, 2). Will this create a trapezium?

Select the image that does not show a right angle. 

Two lines are perpendicular if they meet at a {{ }} angle.

What is the name of the shape which is to the left of the hexagon?

What is the name of the shape which is below the circle?

What are the coordinates of the star? Remember to use brackets and a comma.

Sofia thinks of a shape. She says it has 4 sides and 4 vertices. It has exactly one pair of parallel lines. What shape could she be describing? 

This lesson will soon be taken down.
