how many triangles are there? Share with your friends Share 3 Shruti Tyagi answered this Dear student, Lets count the number of triangles where side of the pentagon is one of the side of the triangle, for each one such side there are 6 triangles. but two of triangle has other side of the pentagon, those will be counted twice so we will count only one triangle for each side, so for five sides,Total 5×5 = 25 such triangles. Now, lets count the triangles where side of the pentagon is not the side of the triangle:There are 5+5 = 10 such triangles, this will be clear by the below diagram(5 green and 5 red triangles). Thus there are total 25+10=35 triangles Regards -3 View Full Answer Masiha Sayed answered this 11 -1 Shreeyansh Gupta answered this 18 2 Diksha answered this 11 1 Diksha answered this 11 is the correct answer -1
