anonymous · Answer

use the Pythagorean triads to prove for right triangle

anonymous · Answer

use pythogarus thereom c^2=a^2+b^2
the sides which satisfies this property is rt angled triangle

cwrw238 · Answer

right angle triangles have property  a^2 = b^2 + c^2  where a is the longest side

anonymous · Answer

answer is D

cwrw238 · Answer

eg A is right angled because  13^2 = 12^2 + 5^2

anonymous · Answer

answer is D it do not satisfies pythogarus thereom c^2=a^2+b^2

anonymous · Answer

is it clear

anonymous · Answer

Life is so much easier when you remember the Pythagorean Triples it's not even funny...

anonymous · Answer

use the pythagores theorem.
