Exploring Area Calculations for Compound Figures

The video tutorial explores the properties and area calculations of common quadrilaterals, focusing on rectangles and squares. It explains how to calculate the area of these shapes using base and height, and extends this knowledge to compound figures by breaking them into simpler shapes. The tutorial emphasizes understanding congruent sides and angles, and using equations to find missing measurements.

What is a rectangle?

• A parallelogram with no right angles.

• A parallelogram with four right angles and two pairs of congruent opposite sides.

• A shape with four sides of equal length.

• A shape with three sides.
