Worked examples
RookieRead and interpret directly.
Triangle angle sum?
- 180°
- 360°
- 90°
- 270°
Answer: 180°. Triangle = 180°.
ProCompare and infer.
Isosceles triangle: base angles 70° each. Apex?
- 40°
- 70°
- 110°
- 180°
Answer: 40°. 180 − 70 − 70.
GuruMulti-step reasoning.
Why is a square classed as both a rectangle AND a rhombus?
- Square has all properties of a rectangle (right angles) AND of a rhombus (4 equal sides) — it's the intersection.
- Coincidence.
- Convention.
- Vague.
Answer: Square has all properties of a rectangle (right angles) AND of a rhombus (4 equal sides) — it's the intersection.. Square = rectangle ∩ rhombus.
