Question

ABCD is a square Determine angle Abc

Answer 1

Answer:

GIVEN - ABCD IS A SQUARE ,where

ac and Bd are the diagonal and angle a =b=c =d = 90 degree

therefore angle abc = 90 degree

Answer 2

Answer:

Step-by-step explanation:In a square all four sides are equal, so are all the angles. So all the angles are 90°

Forming triangle DCA, the three sides are

AD, DC and CA

Since AD = DC, triangle DCA is an isosceles triangle.

So angle DCA = (180 - 90) / 2 = 45°
