Front

How many sides does a hexagon have?

Back

A hexagon has six sides.

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.

Front

What is the difference between a convex and concave polygon?

Back

A convex polygon has all interior angles less than 180 degrees, while a concave polygon has at least one interior angle greater than 180 degrees.

Front

What are the coordinates of the pre-image if the image points are A' (2, 3), B' (-3, 8), C' (-7, 3) and the transformation is (x - 6, y + 8)?

Back

The pre-image points are A (8, -5), B (3, 0), C (-1, -5).

Front

What is a scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

If a figure is enlarged by a scale factor of 3, what happens to its dimensions?

Back

All dimensions of the figure are multiplied by 3.

Front

If a figure is reduced by a scale factor of 1/3, what happens to its dimensions?

Back

All dimensions of the figure are multiplied by 1/3.

Front

What are the coordinates of point A(-2, 2) after dilation with a scale factor of 2?

Back

A' (-4, 4).

Front

What are the coordinates of point B(3, 2) after dilation with a scale factor of 2?

Back

B' (6, 4).

Front

What is the formula for the area of a polygon?

Back

The area of a polygon can be calculated using various formulas depending on the type of polygon, such as A = 1/2 * Perimeter * Apothem for regular polygons.
