Answer 1

Answer:

yes

Step-by-step explanation:

because all the three sides sum is greater

(8+20) (25+8) (20+25)

Answer 2

Answer:

Nope

Step-by-step explanation:

You need to apply Pythagorean theorem to check whether the Triangle is right angled or not

According to the pythagorean thm,

If a , b ,c are the sides of a triangle then,

$a^{2} +b^{2} =c^{2}$

therefore just put

a=8 and b=20 and c=25

now

(8)^2 +(20)^2 = 64+400 = 464......(1)

and (25)^2 = 625  ......(2)

Since 464 is not equal to 625

this triangle is not right angled

hey mate
