2D Shape Attribute Review 2

The point where two sides meet on a 2D shape are called...

• Vertices

• Angles

• Sides

• Corners

Answer explanation

The correct term for the point where two sides meet on a 2D shape is 'vertices'. While 'corners' is a common synonym, 'vertices' is the precise mathematical term used in geometry.

The corners on the INSIDE of a 2D shape are called...

• Vertices

• Sides

• Angles

• Circles

Answer explanation

The corners on the inside of a 2D shape are called angles. Angles are formed where two sides meet, while vertices refer to the points themselves, and sides are the line segments that make up the shape.

The outlines of 2D Shapes are called...

• Borders

• Vertices

• Angles

• Sides

Answer explanation

The outlines of 2D shapes are referred to as 'sides'. Each side connects to form the shape, while 'vertices' are the corners, 'angles' are the measures between sides, and 'borders' is a more general term not specific to shapes.

True or false: This is a Polygon

• True

• False

Answer explanation

The statement is false because a polygon is defined as a closed figure with straight sides. If the figure in question does not meet this definition, it cannot be classified as a polygon.

True or False: This is a Polygon

• True

• False

Answer explanation

A polygon is defined as a closed figure with straight sides. Since the statement confirms it is a polygon, the answer is True.

True or False: This is a Polygon

• True

• False

Answer explanation

The statement is False because a polygon is defined as a closed figure with straight sides. If the figure in question does not meet this definition, it cannot be classified as a polygon.

True or False: This is a Polygon

• True

• False

Answer explanation

The statement is False because a polygon is defined as a closed figure with straight sides. If the shape in question does not meet this definition, it cannot be classified as a polygon.

True or False: This is a Polygon

• True

• False

Answer explanation

The statement is False because a polygon is defined as a closed figure with straight sides. If the figure in question does not meet this definition, it cannot be classified as a polygon.

How many vertices?

• 3

• 8

• 6

• 4

Answer explanation

A shape with 4 vertices is a quadrilateral. The other options (3, 6, 8) correspond to triangles, hexagons, and octagons, respectively. Therefore, the correct answer is 4.

How many vertices?

• 9

• 2

• 4

• 3

Answer explanation

A shape with 4 vertices is a quadrilateral. The other options (9, 2, 3) do not correspond to any common geometric shape with that number of vertices. Therefore, the correct answer is 4.
