Test: Geometry - 1 - Class 4 MCQ

Geometry is the branch of mathematics concerned with shapes, sizes, positions, and properties of objects in space.

(C) : Perimeter of P = (14 × 2) units = 28 units

Perimeter of Q = (18 × 2) units = 36 units

Perimeter of R = (16 × 2) units = 32 units

Perimeter of S = (20 × 2) units = 40 units

Ascending order of figures according to their perimeters, is P, R, Q and S.

Solution:

The correct answer is both (i) and (ii). 

• In figure (i), the lines cross at a certain point.
• In figure (ii), the lines also intersect.
• Therefore, both figures show intersecting lines.

The only line in the image that is parallel to line AB is line CD, meaning they will never intersect at any point

1. T – Has two parallel horizontal lines (top horizontal and the base of vertical stem): ✅

2. R – No parallel lines; the slanted and curved parts don’t count: ❌

3. I – Has two parallel vertical lines (the sides of the letter): ✅

4. C – The arcs are curved; no straight parallel lines: ❌

5. K – Has slanted lines meeting at a point; no parallel lines: ❌

The net of a cylinder has:

• 2 circular faces (top and bottom)
• 1 rectangular face that wraps around the side

In total, a cylinder's net consists of 3 faces.

In a cuboid, the following is true about its faces:

• Opposite faces are identical in shape and size.
• A cuboid has rectangular faces, not circular or triangular.
• Each face is a rectangle, and adjacent faces meet at right angles.

Answer: 90°

The net of an open box has 5 faces. This includes:

• 1 base
• 4 sides

Since the top is open, it does not count as a face. Thus, the total is 5 faces.
