10 angle bisector questions and other geometry questions for SSC CGL Set 37 - answering time 15 mins

Problem 1.

Two chords AB and CD of a circle with centre at O intersect each other at point P. If the two non-overlapping angles $\angle AOD=100^0$ and $\angle BOC=70^0$ then the value of $\angle APC$ is,

  1. $80^0$
  2. $75^0$
  3. $95^0$
  4. $85^0$

Problem 2.

The radii of two concentric circles are 13 cm and 8 cm. AB is a diameter of the larger circle and BD is a tangent to the smaller circle touching it at D and intersecting the larger circle at E. The length of line segment AD is,

  1. 17 cm
  2. 19 cm
  3. 18 cm
  4. 20 cm

Problem 3.

In a $\triangle ABC$, AD is perpendicular dropped on side BC and E is a point on AD so that AE : ED = 5 : 1. If $\angle BAD = 30^0$ and $\tan \angle ACB = 6\tan \angle DBE$, then $\angle ACB$ is,

  1. $15^0$
  2. $30^0$
  3. $45^0$
  4. $60^0$

Problem 4.

In $\triangle ABC$ when the points D and E on sides AB and AC are joined, the line DE turns out to be parallel to BC and also bisects the triangle into two equal areas. Under this condition, the ratio of DB : AB is,

  1. $1 : 2$
  2. $\sqrt{2} : 1$
  3. $(\sqrt{2} - 1) : \sqrt{2}$
  4. $1 : \sqrt{2}$

Problem 5.

The external bisectors of $\angle B$ and $\angle C$ of $\triangle ABC$ with AB and AC extended to E and F respectively, meet at point P. If $\angle BAC=100^0$, then $\angle BPC$ is,

  1. $40^0$
  2. $50^0$
  3. $80^0$
  4. $100^0$

Problem 6.

Angle between the two internal bisectors of angles $\angle B$ and $\angle C$ in $\triangle ABC$ is $120^0$. The $\angle A$ is,

  1. $20^0$
  2. $90^0$
  3. $30^0$
  4. $60^0$

Problem 7.

Two chords AB and CD of a circle with centre O intersect at point P. If $\angle ADP=23^0$ and $\angle APC=70^0$ then $\angle BCD$ is,

  1. $47^0$
  2. $45^0$
  3. $67^0$
  4. $57^0$

Problem 8.

In $\triangle ABC$ AD is the internal bisector of the $\angle A$ meeting the side BC at D. If BD=5 cm and BC=7.5 cm, the ratio of AB : AC is,

  1. 1 : 2
  2. 2 : 1
  3. 4 : 5
  4. 3 : 5

Problem 9.

P and Q are two points on a circle with centre at O. R is a point between P and Q on the minor arc formed by P and Q. If tangents to the circle at P and Q meet at point S with $\angle PSQ = 20^0$, then $\angle PRQ$ is,

  1. $80^0$
  2. $100^0$
  3. $160^0$
  4. $200^0$

Problem 10.

Two circles intersect each other at points A and B. A straight line parallel to AB intersects the two circles consecutively at C, D, E and F. If CD=4.5 cm the length of line segment EF is,

  1. 4.5 cm
  2. 9 cm
  3. 1.5 cm
  4. 2.25 cm
