ACT SAT Prep How to determine the length of a parallelogram given a side and perimeter

The video tutorial explains how to find the length of line UT in a parallelogram RSTU with a given perimeter of 42 units. It covers the properties of parallelograms, such as congruent opposite sides and angles, and uses these properties to set up an equation. The equation is solved to find the length of UT, demonstrating the application of geometry concepts in problem-solving.

Explain the relationship between the angles in a parallelogram.

• All angles are equal

• Opposite angles are equal

• All angles are right angles

• Adjacent angles are equal

How do you calculate the perimeter of a parallelogram?

• Add all sides

• Multiply the length by the width

• Add the lengths of opposite sides

• Use the formula 2(l + w)
