Answer 2

Answer with Step-by-step explanation:

Given

$\angle ABC+\angle ACB=90^{\circ}$

In triangle ABC

$\angle ABC+\angle ACB+\angle BAC=180^{\circ}$

By using triangle angles sum property

Substitute the values then we get

$90+\angle BAC=180$

$\angle BAC=180-90$

By using subtraction property of equality

$\angle BAC=90^{\circ}$

When the angle between two sides is equal to 90 degrees then the two sides are perpendicular.

Therefore, CA is perpendicular to AB.

Hence, proved.
