AD = 10 units
BD = 12 units
<u><em>Explanation:</em></u>
<u>1- getting AD:</u>
In an isosceles triangle, the two non-parallel sides are equal.
It is given that trapezium ABCD is isosceles which means that AD = BC
<u>We are given that:</u>
BC = 10 units
<u>Therefore:</u>
AD = BC = 10 units
<u>2- getting DB:</u>
In an isosceles trapezium, the diagonals are congruent
Since the given trapezium is isosceles and AC and BD are its diagonals, therefore:
AC = BD
AC = 12 units
BD = AC = 12 units
Hope this helps :)
Answer:
