Geometric Properties to Find the Perimeter of Plane Figures (Part 2)

The video tutorial explains how to calculate the perimeter of a rhombus when only one side length is known. It highlights the geometric property that all sides of a rhombus are equal, allowing the calculation of the perimeter by multiplying the known side length by four. The lesson concludes with a summary of the method used to determine the perimeter based on geometric properties.

What is the main challenge presented in the introduction regarding the rhombus?

• Finding the area of the rhombus

• Calculating the perimeter with unknown sides

• Determining the angles of the rhombus

• Identifying the type of quadrilateral

What is a key property of a rhombus that helps in calculating its perimeter?

• Opposite sides are parallel

• All angles are right angles

• All sides are equal in length

• Diagonals are equal

If one side of a rhombus is 10 inches, what is the length of each of the other sides?

• 5 inches

• 10 inches

• 15 inches

• 20 inches

How do you calculate the perimeter of a rhombus if one side is known?

• Add the length of one side four times

• Multiply the length of one side by two

• Add the length of two sides and multiply by two

• Multiply the length of one side by four

What is the perimeter of a rhombus with each side measuring 10 inches?

• 50 inches

• 20 inches

• 30 inches

• 40 inches
