Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle with all sides of different lengths.

Front

How do you find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

What happens to the coordinates of a point (x, y) when it is rotated 90° clockwise about the origin?

Back

The new coordinates become (y, -x).

Front

What is a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What is the difference between a square and a rectangle?

Back

A square has all sides equal, while a rectangle has opposite sides equal.

Front

How do you classify triangles based on angles?

Back

Triangles can be classified as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°).

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width).
