& T2

&T3

. Label as ∆ABC, such that angleC=90° in each

case.Measure the sides a,b,c compute a²,b²,c². P. T C2 = a² + b ² in each case.
​

Answer 1

Answer:

Give a right angle triangle ABC with right angled at C. `angleC=90^(@)` and a,b,c are lengths of corresponding sides. `(b gt a)`. <br> `cos(A-B)` will be equal to
