Olympiad Test: Geometrical Shapes - 1 - Class 4 MCQ

The shape in Option B is a square, which has four equal sides and four equal corners (90-degree angles at each corner). This matches the criteria described in the question.

• Option A: The red circle does not have corners or sides, so it doesn't fit the description.
• Option C: The orange triangle has three sides and three corners, not four.
• Option D: The diamond shape has four sides, but the angles are not equal (it is not a square).

Thus, the correct answer is Option B: Green Square.

The shape with three sides is a triangle.

• Option A (Diamond) has four sides.
• Option B (Rhombus) also has four sides.
• Option C (Triangle) has three sides, which matches the description in the question.
• Option D (Rectangle) has four sides.

Therefore, the correct answer is Option C: Triangle.

 (Triangle)

A sphere is a 3D shape, meaning it has three dimensions: length, width, and height. It is perfectly round in all directions.

• Option A (Circle) is a 2D shape, as it only has length and width.
• Option C (Triangle) is also a 2D shape with length and width.
• Option D (Rectangle) is a 2D shape with length and width.

Therefore, the correct answer is Option B: Sphere.

A cone has two faces: one curved surface and one flat circular base. The curved surface extends from the base to the apex, while the flat circular base is perpendicular to the curved surface.

A rectangle is the only shape in the given options that has 4 sides.

• Option A (Triangle) has 3 sides.
• Option B (Circle) has no sides.
• Option C (Hexagon) has 6 sides.
• Option D (Rectangle) has 4 sides, making it the correct answer.

Thus, the correct answer is Option D: Rectangle.

A cylinder () is like a can of soup, having two circular faces and a tube-like shape.

• Option A (Sphere) is round and 3D, like a ball, but not like a can.
• Option C (Cube) has square faces, which is not the shape of a can.
• Option D (Cone) has a pointed top, which is also not the shape of a can.

Thus, the correct answer is Option B: Cylinder.

A dice is a small, square-shaped object with six faces, and each face is a square. This shape is a cube, which has six equal square faces.

Thus, the correct answer is (a) Cube.

The shape shown in the image appears to have a smooth, round surface without any visible edges or vertices, which describes a sphere. A sphere is a perfectly round 3D shape, and the lines in the image suggest the curved nature of a sphere.

• Option A (Circle) is 2D, not 3D.
• Option B (Cylinder) has flat circular faces and a curved surface, which is not represented here.
• Option D (Cone) has a circular base and a pointed top, which doesn't match the image either.

Thus, the correct answer is Option C: Sphere. Thank you for your patience!

A cube () is a 3D shape with six equal square faces, and it looks like a block of cheese.

• Option B (Cylinder) is not the typical shape of a block of cheese.
• Option C (Cone) is a conical shape, which is not commonly associated with cheese blocks.
• Option D (Sphere) is round, which is not the typical shape for cheese blocks.

Thus, the correct answer is Option A: Cube.

The shape of a matchbox is typically a rectangular cuboid or simply a cuboid. It has six rectangular faces, with opposite faces being equal in size.

Thus, the correct shape is a cuboid.
