Polygons on a Coordinate Plane-Practice 1

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

What are the properties of a rectangle?

Back

A rectangle has four right angles, opposite sides that are equal in length, and the diagonals are equal in length.

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

What are coordinates in a coordinate plane?

Back

Coordinates are a pair of numbers (x, y) that define a point's position on a two-dimensional grid.

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you identify the fourth vertex of a rectangle given three vertices?

Back

Use the properties of rectangles to find the missing vertex by ensuring opposite sides are equal.

Front

What is the area of a rectangle with vertices at (2,2), (2,-4), (-5,-4), and (-5,2)?

Back

Area = 26 units².

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
