Semester Review - Coordinate Plane Perimeter & Areas

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

How do you find the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is a trapezoid?

Back

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

Front

How do you calculate the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height.

Front

What is the distance formula in the coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

How do you find the area of a polygon?

Back

Divide the polygon into simpler shapes (like triangles and rectangles), calculate their areas, and sum them up.

Front

What is the significance of the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as a reference point for all other points.
