Hey
I have this right angle triangle with 'a' as the adjacent, '8' as the opposite and 'h' as the hypotenuse.
Why do a and h satisfy the equation a*h=8^2
Please help
They don't.
If it is a right triangle, then you know . You could solve your original equation for a, then plug it into the pythagorean theorem and solve for h. This would mean h MUST be approximately 10.176. Plugging that back into your original equation, you would find a MUST be approximately 6.289.
On the other hand, if you sketch a quick picture of what you are given about your triangle, then you can see that there are no such limitations on a and h. As leg a gets longer, hypotenuse h gets longer too. In fact, ANY values for a and h that satisfy the pythagorean theorem would work. Thinking of it another way, none of the triangle congruence theora would be satisfied if I had another triangle with the characteristics you describe. Hence, my triangle might not be congruent and might NOT have the lengths calculated above.
