Geometry A Pre-Test '25

Front

What is the equation of a line given a point and a slope?

Back

The equation of a line can be expressed in point-slope form: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

How do you find the value of x in a geometric diagram?

Back

To find the value of x, use the properties of angles, triangles, or other geometric figures, applying relevant theorems and equations.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

How do you calculate the mean of a set of numbers?

Back

To calculate the mean, add all the numbers together and divide by the total count of numbers.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal.

Front

What is the point-slope form of a linear equation?

Back

The point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

What is the relationship between vertical angles?

Back

Vertical angles are congruent, meaning they have the same measure.

Front

How do you identify alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal.

Front

What is the formula for finding the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1) between two points (x1, y1) and (x2, y2).

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.
