Answer questions about the provided image.

Analysis of the Image Content:

The image contains a mathematics worksheet with several geometry problems related to perpendicular lines. It includes instructions and visual representations for exercises numbered 1 through 6.

Problem 1:

Instruction: "Draw a line through point C perpendicular to line AB."

Visual: A grid with points A, B, and C. Line AB is drawn horizontally. Point C is located above and to the right of the midpoint of AB.

Problem 2:

Instruction: "Draw a line through point C perpendicular to line AB."

Visual: A grid with line AB drawn diagonally from bottom left to top right. Point C is located to the right and slightly below the midpoint of AB.

Problem 3:

Instruction: "Draw a line through point C perpendicular to line AB."

Visual: A grid with line AB drawn horizontally. Point C is located to the left and slightly above the midpoint of AB.

Problem 4:

Instruction: "Draw a line through point C perpendicular to line AB."

Visual: A grid with line AB drawn diagonally from top left to bottom right. Point C is located to the right and below the midpoint of AB.

Problem 5:

Instruction: "Indicate pairs of perpendicular lines."

Visual: A starburst pattern of eight lines (labeled a, b, c, d, e, f, and two unlabeled) radiating from the center of a grid. The lines appear to be at various angles.

Problem 6:

Instruction: "Indicate pairs of perpendicular lines."

Visual: A grid with four lines labeled a, b, c, and d, and two additional lines labeled e and f. Lines 'a' and 'b' appear parallel. Lines 'b' and 'c' appear parallel. Lines 'a' and 'c' appear parallel. Line 'd' is horizontal. Lines 'e' and 'f' are also present.

Textual Content:

The title reads "Практическая работа «Перпендикулярные прямые» Вариант 2" (Practical work "Perpendicular lines" Variant 2).

Additional text includes instructions and mathematical terms in Russian, such as "Математика 6" (Mathematics 6), "Через точку С проведите прямую, перпендикулярную прямой АВ." (Through point C, draw a line perpendicular to line AB.), and "Укажите пары перпендикулярных прямых." (Indicate pairs of perpendicular lines.).
