Triangles

Find out whether given sizes of the angles can be interior angles of a triangle:

a) 23°10',84°30',72°20'
b) 90°,41°33',48°37'
c) 14°51',90°,75°49'
d) 58°58',59°59',60°3'

Result

a)



b)



c)



d)




Solution:

a)23+10/60+84+30/60+72+20/60=180a) 23+10/60+84+30/60+72+20/60=180
b)90+41+33/60+48+37/60=180.167180b) 90+41+33/60+48+37/60 = 180.167 \ne 180
c)14+51/60+90+75+49/60=180.167180c) 14+51/60+90+75+49/60 = 180.167 \ne 180
d)58+58/60+59+59/60+60+3/60=179180d) 58+58/60+59+59/60+60+3/60= 179 \ne 180



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
