11/22/24 AM Warm Up (Prob, Similarity, Area of Comp., Dilation)

Front

What is dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but not its shape. It is defined by a center point and a scale factor.

Front

How do you calculate the new coordinates of a point after dilation?

Back

To find the new coordinates after dilation, multiply each coordinate of the point by the scale factor.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the area of a semicircle?

Back

The area of a semicircle is calculated using the formula: Area = (1/2) × π × r², where r is the radius.

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

What is the theoretical probability of flipping a coin?

Back

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one event does not affect the occurrence of the other.

Front

How do you find the total area of a composite figure?

Back

To find the total area of a composite figure, calculate the area of each individual shape and then sum them up.

Front

What is the scale factor in dilation?

Back

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

Front

What is the relationship between experimental probability and theoretical probability as trials increase?

Back

As the number of trials increases, the experimental probability tends to get closer to the theoretical probability.
