Answer 1

Answer:

all angles of square =90°

<cda =90° because <d = 90 °

I am sorry if I was wrong

Answer 2

Answer:

DC || AB , so

angle CAB =angle ACB. ( alternate interior angles)

also

angle CAD = angle ACB ( AD = CD so , angles opposite to equal sides of a triangle are equal)

from above .

angle CAD =angle CAB -1

now angle CAD +angle CAB = 90 ( angles of a square)

angle CAD + angle CAD = 90. ( using eq 1)

2 angle CAD = 90

angle CAD = 45
