Create a series of 16:9 cards. White background. Use no more than two to three colors per card. Outline: Thin black line around the outer contour of the shapes. Alignment strictly on an invisible horizontal grid of three columns, so that objects on different cards stand directly below each other. Card 1 - "Types of Cones" Left object (blue silhouette): Tall, straight cone. Axis clearly perpendicular to the base. Italic caption below: "right cone". Center object (orange silhouette): Slanted cone. Apex noticeably shifted to the right of the base's center. Axis drawn with a dashed line, showing the angle of inclination. Caption: "oblique cone". Right object (mint silhouette): Truncated cone. Top radius about half the bottom radius. Side surface shown with light hatching, imitating a trapezoid. Caption: "truncated cone". Card 2 - "Sections of a Cone" Title: Large in the center at the top - "Sections of a Cone". Top row (side view): Three small colored cones (blue, orange, yellow) in a line. A translucent white section plane passes through each. Left: Plane is parallel to the ground. A thin colored circle contour is visible inside the cone. Center: Plane goes vertically through the apex. A parabolic side face and base are visible, forming a triangle. Right: Diagonal plane. An elongated ellipse is visible inside. Bottom row (front view / cutaway): Directly below each cone is its enlarged cross-section (pure geometry): Below the left - a perfect circle. Below the center - an isosceles triangle. Below the right - an ellipse. Labels: Small print directly below the bottom row: "horizontal (circle)", "vertical (triangle)", "inclined (ellipse)". Section lines are indicated by thin hachure marks on the cone bodies. Card 3 - "Area and Volume of a Cone" Left - blue background block, right - mint. Left part (Right Cone): Glossy blue cone slightly taller than it is wide. Below it, the formula for the cone's surface area and the formula for the cone's volume. Right part (Truncated Cone): Mint truncated cone. Bottom radius R wider than top radius r, slant height l along the beveled edge. Below it, the formula for the total surface area of the cone, the formula for the volume of a truncated cone.
