Question

Square ABCD has diagonals AC¯¯¯¯¯

Answer 1

Answer:

option (c)

Step-by-step explanation:

Given,

ABCD is a square.

AC and BD are diagonals

We know that,

Sides of the square make 90 degrees with each other.

And Diagonals bisect the opposite angles of the square.

Now,

$\angle ABD = \dfrac{\angle ABC}{2}$

$\angle ABC = 90^\circ$

$\angle ABD = \dfrac{\angle ABC}{2}$

$\angle ABD = \dfrac{90^\circ}{2}$

$\angle ABD = 45^\circ$

Hence, option (c) is correct.
