C2 C3 c4 c5 C6 R1 Before starting the new concept for triangle Let's quickly find the answer for R2 R3 R4 R5 21*15 315

Find the no of triangle 1 2 3 Find the total number of interval 1+2+3 6 So our answer will be 6

Find the no of triangle: 1 2 3 4 As it is clear from the image that there will be 4 interval in which this image will be divided hence total number of triangle will be (1+2+3+4) 10

Find the no of triangle As it is clear from the image that there will be 4 interval in AD line hence total no of triangle will be (1+2+3+4) 10 Similarly the above given line gives three interval hence total triangle will be (1+2+3) 6 So total number of triangle for it will be 6+10 16

Find the no of triangle: As it is clear from the image that there will be 4 interval in AD line hence total no of triangle will be (1+2+3+4) 10 Similarly the above given line from AD, has three interval hence total triangle will be (1+2+3) 6 and above that also has three interval hence total triangle will be So total number of triangle 10+6+6 22

Find the no of triangle 1. Count the smaller no of triangle and multiply with 2, hence 2*4 8 2. Count the smaller no of triangle and multiply with 2, hence 2*6 12 3. Since this figure has two square, so we need to count each figure individually and we will get answer Bigger square has 8 triangle hence total triangle in it is 8*2 16 Similarly for smaller figure triangle are 8*2 16 So total triangle will be 16+16 32

Find No of Triangle: Following our earlier trick We know that Triangle BDF,CEF and ADE will be having 3 triangle each so total 9 Then DEF and ABC will be two more hidden triangle so total number of triangle will be 9+2 11

Q. Find the number of triangles in the given figure This is questions asked in one exam A) 25 B) 27 C) 29 D) 31 AGB, OEF and HCD are 3*3 -9 OEGB and OFCH are 8*2- 16 Now ABE, EBF, EFC and FCD are the remaining Hence total 9+16+4 = 29 triangle
