Question

5. AC and BD are the two diagonals of a square ABCD which intersect at O. AC is one diagonal of
a square ABCD. Find the measure of DOA​

Answer 1

The measure of angle BOA=90 degrees

Step-by-step explanation:

Given:ABCD is a square

AC and BD are diagonals of square ABCD.

Properties of square:

1.Each angle of square is equal to 90 degrees.

2.All sides of square are equal.

3.Diagonals of square are equal .

4.Diagonals of square bisect perpendicularly.

Diagonal AC and diagonal BD of square ABCD intersect at point O.

By property of square

Angle AOB=Angle BOC=Angle COD=Angle AOD=90 degrees.

Hence, the measure of angle BOA=90 degrees

Answer 2

$\huge \star\mathfrak \red{Answer!!}$

All angles in a square are 90

AC is a diagonal so it bisects angle a . in this way angle d is also bisected.

AC is again bisected by DB so

DOA=90
