1.	If 3 sides of a triangle are of lengths12 cm, 8 cm and 17 cm. then which type of triangle is this ?
Answer» Since, `7+8 gt 12` `:.` Triangle is possible. Now, `("longest side")^(2)=(12)^(2)=144` and sum of squares of other sides `=(7)^(2)+(8)^(2)=49+64=113` Since `("longest side")^(2) gt` sum of squares of two other sides. `:.` It is an obtuse angled triangle.
