SY25 Geometry IA2 (Final) Review A

Front

What is the formula for the area of a circle?

Back

The area of a circle is given by the formula: A = πr², where r is the radius.

Front

What is the equation of a circle with center (h, k) and radius r?

Back

The equation of a circle is (x - h)² + (y - k)² = r².

Front

How do you find the area of a shaded region in a geometric figure?

Back

To find the area of a shaded region, subtract the area of the unshaded part from the total area of the figure.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure during dilation.

Front

How do you calculate the probability of an event?

Back

Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the sample space in probability?

Back

The sample space is the set of all possible outcomes of a probability experiment.

Front

What is the definition of dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but not its shape.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

How do you determine the coordinates of a point after dilation?

Back

To find the coordinates after dilation, multiply the original coordinates by the scale factor.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: A = 1/2 * base * height.
