Morris: Geometry Midterm Exam

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What is the formula for the slope of a line?

Back

The slope (m) of a line is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How do you find the slope from the equation of a line in standard form?

Back

To find the slope from the equation Ax + By = C, rearrange to slope-intercept form (y = mx + b) to identify m.

Front

What is the relationship between the slopes of intersecting lines?

Back

Intersecting lines have different slopes and will cross at one point.

Front

What is the measure of each interior angle in an equilateral triangle?

Back

Each interior angle in an equilateral triangle measures 60 degrees.

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle is given by A = (1/2) * base * height.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, a^2 + b^2 = c^2, where c is the hypotenuse.
