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