Q:

Find the number of triangles in the given figure?

A) 16 B) 22
C) 28 D) 32
 
Answer & Explanation Answer: C) 28

Explanation:

The simplest triangles are AFJ, FJK, FKB, BKG, JKG, JGC, HJC, HIJ, DIH, DEI, EIJ and AEJ i.e. 12 in number.

The triangles composed of two components each are JFB, FBG, BJG, JFG, DEJ, EJH, DJH and DEH i.e. 8 in number.

The triangles composed of three components each are AJB, JBC, DJC and ADJ i.e. 4 in number.

The triangles composed of six components each are DAB, ABC, BCD and ADC i.e. 4 in number.

Thus, there are 12 + 8 + 4 + 4 = 28 triangles in the figure.

Q:

Find the minimum number of straight lines required to make the given figure.

A) 13 B) 15
C) 17 D) 19
 
Answer & Explanation Answer: A) 13

Explanation:

  

The horizontal lines are IJ, AB, EF, MN, HG, DC and LK i.e. 7 in number.

The vertical lines are AD, EH, IL, FG, BC and JK i.e. 6 in number.

Thus, there are 7 + 6 = 13 straight lines in the figure.

Q:

Find the number of triangles in the given figure?

A) 11 B) 13
C) 15 D) 17
 
Answer & Explanation Answer: C) 15

Explanation:

We may label the figure as shown.

The Simplest triangles are AFB, FEB, EBC, DEC, DFB and AFD i.e 6 in number.

The triangles composed of two components each are AEB, FBC, DFC, ADE, DBE and ABD i.e 6 in number.

The triangles composed of three components each are ADC and ABC i.e 2 in number.

There is only one triangle i.e DBC which is composed of four components.

Thus, there are 6 + 6 + 2 + 1 = 15 triangles in the figure

Q:

What is Latus Rectum of Parabola?

A) line segment B) vertex
C) focus D) major axis
 
Answer & Explanation Answer: A) line segment

Explanation:

As parabola is a locus of a point, which moves so that its distance from focus and directrix is always equal.

 

The latus rectum of a conic section is the chord (line segment) that passes through the focus, is perpendicular to the major axis and has both endpoints on the curve. The length of the latus rectum is determined differently for each conic.

The length of a parabola's latus rectum is 4p, where p is the distance from the focus to the vertex.
