10 Geometry problems for SSC CGL Set 1 - time to solve 12 mins

Problem 1.

$\triangle ABC$ is an isosceles triangle with $AB=AC$ and $AD$ as the median to base $BC$. If $\angle ABC = 35^0$, the $\angle BAD$ is

  1. $70^0$
  2. $35^0$
  3. $55^0$
  4. $110^0$

Problem 2.

In isosceles triangle $\triangle FGH$,  $FG \lt 3$ cm and $GH = 8$cm. Then the correct relation is,

  1. $GH = FH$
  2. $GH \lt FH$
  3. $GF = GH$
  4. $FH \gt GH$

Problem 3.

The sum of three altitudes of a triangle is,

  1. equal to the sum of three sides
  2. twice the sum of sides
  3. greater than the sum of sides
  4. less than the sum of sides

Problem 4.

The length of 3 sides of a triangle are, 6cm, 8cm and 10cm. The length of the median to the greatest side is then,

  1. 5cm
  2. 8cm
  3. 4.8cm
  4. 6cm

Problem 5.

$O$ and $C$ are the Orthocenter and the Circumcenter of an acute angled triangle $\triangle PQR$ respectively. The points $P$ and $O$ are joined and produced to meet the side $QR$ at $S$. If $\angle QCR = 130^0$ and $\angle PQS = 60^0$ then $\angle RPS$ is,

  1. $100^0$
  2. $35^0$
  3. $30^0$
  4. $60^0$

Problem 6.

If $I$ is the incenter of $\triangle ABC$,  $\angle ABC = 65^0$ and $\angle ACB = 55^0$, the $\angle BIC$ is,

  1. $110^0$
  2. $120^0$
  3. $130^0$
  4. $140^0$

Problem 7.

If the median drawn on the base of a triangle is half its base, the triangle will be,

  1. acute-angled
  2. obtuse-angled
  3. right-angled
  4. equilateral

Problem 8.

In a right angled triangle the product of its two sides equals half of the square of the third side which is the hypotenuse. One of the acute angles must then be,

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

Problem 9.

In $\triangle ABC$, two points $D$ and $E$ are taken on the lines $AB$ and $BC$ respectively in such a way that $AC$ is parallel to $DE$. The $\triangle ABC$ and $\triangle DBE$ are then,

  1. always similar
  2. always congruent
  3. similar only if $D$ lies outside the line segment $AB$
  4. congruent only if $D$ lies outside the line segment $AB$

Problem 10.

$AD$ is a median of $\triangle ABC$ and $O$ is the centroid such that $AO = 10cm$. Length of $OD$ (in cm) is,

  1. 7
  2. 5
  3. 4
  4. 2
