10.3-10.5 Flashcardizz Review (Geometry)

Front

What is the formula for the area of a regular polygon?

Back

The area (A) of a regular polygon can be calculated using the formula: A = (1/2) * Perimeter * Apothem.

Front

What is an apothem in a polygon?

Back

An apothem is a line segment from the center of a regular polygon perpendicular to one of its sides.

Front

What is the relationship between the radius and the apothem in a regular polygon?

Back

The radius is the distance from the center to a vertex, while the apothem is the distance from the center to the midpoint of a side.

Front

How do you find the area of a triangle given its base and height?

Back

The area (A) of a triangle can be calculated using the formula: A = (1/2) * base * height.

Front

What is the significance of the central angle in a regular polygon?

Back

The central angle is the angle formed at the center of the polygon by two radii drawn to two adjacent vertices.

Front

What is the area ratio of two similar figures?

Back

The area ratio of two similar figures is equal to the square of the ratio of their corresponding side lengths.

Front

If the height of a trapezoid is doubled, how does the area change?

Back

If the height of a trapezoid is doubled, the area also doubles.

Front

What is the formula for the area of a trapezoid?

Back

The area (A) of a trapezoid can be calculated using the formula: A = (1/2) * (Base1 + Base2) * height.

Front

What does it mean for two polygons to be similar?

Back

Two polygons are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is the formula for the area of a circle?

Back

The area (A) of a circle can be calculated using the formula: A = π * r^2, where r is the radius.
