What is the sine function in relation to a right triangle?

Back

The sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine function in relation to a right triangle?

Back

The cosine function is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the formula to find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the types of transformations that preserve congruence?

Back

Reflections, translations, and rotations preserve congruence.

Front

What is a dilation in geometry?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What is the measure of a full circle in degrees?

Back

A full circle measures 360 degrees.

Front

How do you calculate the measure of an arc in a circle?

Back

The measure of an arc can be calculated using the formula: Arc Measure = (Central Angle/360) * Circumference.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are always equal.
