What is the formula to calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

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

Back

The sum of the interior angles of a triangle is 180°.

Front

What does the Triangle Sum Theorem state?

Back

The Triangle Sum Theorem states that the sum of all angles in a triangle is 180°.

Front

What are exterior angles in relation to a triangle?

Back

Exterior angles are formed by one side of a triangle and the extension of an adjacent side.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint called the vertex.

Front

What is the difference between acute, obtuse, and right angles?

Back

Acute angles are less than 90°, right angles are exactly 90°, and obtuse angles are greater than 90° but less than 180°.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.
