How many triangles are there in the given figure?
Except in figure (1), in all others the circle has been divided into four equal parts.
The second figure is the upside down image of the first figure and the shaded portion moves to the opposite side.
From first figure to second figure the design rotates through 90° clockwise and becomes double.
In this question, the sets of numbers given in the alternatives are represented. The columns and rows of Matrix I are numbered from 0 to 4 and that ofMatrix II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g., A can be represented by 02,10, etc.,and 'B' can be represented by 57, 65, etc. Similarly you have to identify the set for the word 'FADE'
Group the given figures into three classes using each figure only once.
1, 6, 9 are figures which are half shaded by slanting lines.
2, 4, 7 are all divided into equal parts (either three or four parts) by straight lines and also have a black circle at the centre.
3, 5, 8 have similar designs and have their four corners shaded black.
Option (a) is correct
What is the number of rectangles in the following figure?
The simplest rectangles are AEHG, EFJH, FBKJ, JKCL and GILD i.e 5 in number.
The rectangles composed of two components each are AFJG and FBCL i.e 2 in number
Only one rectangle namely AFLD is composed of three components and only one rectangle namely ABCD is composed of five components.
Thus, there are 5 + 2 + 1 + 1 = 9 rectangles in the given figure.
