Area of Polygons

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height

Front

How do you find the height of a trapezoid if the area and bases are known?

Back

Rearrange the area formula: Height = (Area * 2) / (Base1 + Base2)

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) * Base * Height

Front

How do you calculate the area of a parallelogram?

Back

Area = Base * Height

Front

What is a diagonal in a polygon?

Back

A diagonal is a line segment connecting two non-adjacent vertices in a polygon.

Front

How do you find the length of a diagonal if given its two parts?

Back

Add the lengths of the two parts: Diagonal = Part1 + Part2

Front

What is the area of a rectangle?

Back

Area = Length * Width

Front

What is the difference between the area and perimeter of a polygon?

Back

Area measures the space inside the polygon; perimeter measures the distance around it.

Front

What is the area of a square?

Back

Area = Side^2

Front

How do you find the area of a rhombus?

Back

Area = (Diagonal1 * Diagonal2) / 2
