What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

Define rotation in geometry.

Back

Rotation is a transformation that turns a figure around a fixed point called the center of rotation.

Front

What is the formula for finding the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

How do you calculate the probability of choosing a card that is a spade or a 7 from a standard deck?

Back

There are 13 spades and 4 sevens, but one of the sevens is a spade. So, P(spade or 7) = (13 + 4 - 1) / 52 = 16/52 = 4/13.

What is the sine function in trigonometry?

Back

The sine function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine function in trigonometry?

Back

The cosine function relates the angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent function in trigonometry?

Back

The tangent function relates the angle of a right triangle to the ratio of the length of the opposite side to the length of the adjacent side.
