Unit 3 Assessment 1

Front

What is the midpoint formula for finding the midpoint of a line segment between two points (x1, y1) and (x2, y2)?

Back

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

Front

How do you find the distance between two points (x1, y1) and (x2, y2) in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What are the properties of a rectangle?

Back

A rectangle has opposite sides that are equal and all angles are right angles (90 degrees).

Front

What is the definition of a vertex in geometry?

Back

A vertex is a point where two or more lines or edges meet.

Front

How do you determine if a shape is a rectangle based on its vertices?

Back

Check if opposite sides are equal and all angles are right angles.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the significance of the coordinates in a Cartesian plane?

Back

Coordinates represent the position of a point in relation to the x-axis and y-axis.

Front

How do you find the coordinates of an endpoint if you know the midpoint and one endpoint?

Back

Use the formula: (x2, y2) = (2 * midpoint_x - x1, 2 * midpoint_y - y1).

Front

What is the definition of a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.
