Question : In $\triangle$ABC, BD and CE are perpendicular to AC and AB respectively. If BD = CE, then $\triangle$ABC is:
Option 1: Equilateral
Option 2: Isosceles
Option 3: Right–angled
Option 4: Scalene
Correct Answer: Isosceles
Solution : Given: In $\triangle$ABC, BD and CE are perpendicular to AC and AB respectively. BD = CE
The area of $\triangle ABC$ $=\frac{1}{2}\times{AB}\times {CE}$ The area of $\triangle ABC$ $=\frac{1}{2}\times{AC}\times {BD}$ $⇒\frac{1}{2}\times{AB}\times {CE}=\frac{1}{2}\times{AC}\times {BD}$ AB = AC (since, BD = CE) So, $\triangle ABC$ is an
Question : The angle subtended by a chord on the centre of a circle is 180°. What will be the angle subtended by the same chord on the circumference of this circle?
Option 1: 120°
Option 2: 95°
Option 3: 90°
Option 4: 45°
Correct Answer: 90°
Solution : The angle subtended by a chord at the centre is twice the angle subtended on the circumference. Angle subtended on the circumference = $\frac{180°}{2}$ = 90° Therefore, the angle subtended by the same chord on the circumference is 90°. Hence, the correct answer is 90°.

Question : The internal bisectors of the angles B and C of a triangle ABC meet at I. If $\angle$BIC = $\frac{\angle A}{2}$ + X, then X is equal to:
Option 1: $60^{\circ}$
Option 2: $30^{\circ}$
Option 3: $90^{\circ}$
Option 4: $45^{\circ}$
Correct Answer: $90^{\circ}$
Solution : $\angle$BIC = $\frac{\angle A}{2}$ + X In $\triangle$ABC, ⇒ $\angle$A + $\angle$B + $\angle$C = $180^{\circ}$ ⇒ $\angle$B + $\angle$C = $180^{\circ}$ – $\angle$A ⇒ $\frac{1}{2}$($\angle$B + $\angle$C) = $90^{\circ}$ – $\frac{\angle A}{2}$ In $\triangle$BIC, ⇒ $\frac{\angle B}{2}$ + $\frac{\angle C}{2}$ + $\angle$BIC = $180^{\circ}$
