2. Two adjacent angles of a parallelogram are always:
- AEqual
- BComplementary (sum 90 deg)
- CSupplementary (sum 180 deg)
- DReflex
Show answer
Answer: C) Supplementary (sum 180 deg)
Adjacent angles of a parallelogram are co-interior between parallel sides, so they add to 180 deg.
3. Opposite sides of a trapezium that are parallel are called its:
- ALegs
- BBases
- CDiagonals
- DVertices
Show answer
Answer: B) Bases
The two parallel sides of a trapezium are its bases; the non-parallel sides are the legs.
4. Three friends describe a shape:
- Ravi: 'It has 4 right angles.'
- Meena: 'Its opposite sides are equal.'
- Joy: 'Its four sides are NOT all equal.'
Which shape fits all three?
- Ravi: 'It has 4 right angles.'
- Meena: 'Its opposite sides are equal.'
- Joy: 'Its four sides are NOT all equal.'
Which shape fits all three?
- ASquare
- BRectangle
- CRhombus
- DTrapezium
Show answer
Answer: B) Rectangle
Four right angles with equal opposite sides is a rectangle or square; 'not all sides equal' rules out the square, leaving a rectangle.
5. A quadrilateral satisfies ALL of these: opposite sides parallel, all sides equal, diagonals perpendicular, but diagonals NOT equal.
What is it?
What is it?
- ASquare
- BRhombus
- CRectangle
- DKite
Show answer
Answer: B) Rhombus
Opposite sides parallel and all sides equal with perpendicular diagonals is a rhombus or square; unequal diagonals rule out the square, leaving a rhombus.
