Being able to name 2D shapes can help us in this lesson.
What is the name of the shape in the picture below?
Think of a shape that has 2 pairs of opposite sides with equal lengths.
From the option above, the shape that has 2 pairs of opposite sides with an equal length is a rectangle.
So the correct option is B: Rectangle
To help work out the name of a shape, think about properties like:
How many sides it has
What sides are the same length
This video looks at the names of 2D shapes.
How many edges does each shape have?
We can count the straight lines around the square.
The square has 4 straight lines around it.
So it has 4 edges.
We can count the straight lines around the kite.
The kite has 4 straight lines around it.
To find the number of edges of a shape, count the number of lines that go around the shape.
