Question

diagonals of a rectangle ABCD intersect at point o. lf AC=8 cm then find BO and if <CAD =35° then find <ACB

Answer 1

measure of, < ACB is90 degree

Answer 2

Diagonals of a rectangle are congruent.

So, AC=BD=8 cm

Also, rectangle is a parallelogram so, the diagonals bisect each other.

Thus, BO=OD=4 cm

Now, AD∣∣CB

So, ∠CAD=∠ACB=35⁰

(Since, alternate interior angles are equal)
