Perimeter & Line Segments on the ACT

Front

What is the formula for the perimeter of a square?

Back

The perimeter of a square is calculated using the formula: P = 4s, where s is the length of one side.

Front

How do you calculate the perimeter of a regular pentagon?

Back

The perimeter of a regular pentagon is calculated using the formula: P = 5s, where s is the length of one side.

Front

If a square has a perimeter of 90 mm, what is the length of one side?

Back

If the perimeter is 90 mm, the length of one side is 90 mm / 4 = 22.5 mm.

Front

What is the relationship between the length of a rectangle and its perimeter?

Back

The perimeter of a rectangle is calculated using the formula: P = 2(l + w), where l is the length and w is the width.

Front

How do you find the midpoint of a line segment?

Back

The midpoint of a line segment is found by averaging the coordinates of the endpoints. For points A(x1, y1) and B(x2, y2), the midpoint M is M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: A = l × w, where l is the length and w is the width.

Front

If a rectangular park has dimensions of 85 feet by 175 feet, what is its perimeter?

Back

The perimeter is calculated as P = 2(85 + 175) = 520 feet.

Front

What is the significance of the term 'line segment' in geometry?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

How do you express the perimeter of a rectangle in terms of its length (l) and width (w)?

Back

The perimeter P can be expressed as P = 2l + 2w.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides: P = a + b + c.
